A retrospective look at history shows the extreme importance that these precise time-measuring instruments had for seafaring. Week after week of disoriented sailing and catastrophic accidents were common occurrences on

of precious human life and valuable cargo were immense. It was often sheer good luck or fortuitous chance that brought famous captains such as Dom Vasco da Gama, Fernando Magellan or Sir Francis Drake to their destinations. All these seamen faced the same problem on their voyages of discovery: they could only guess at their precise position on the high seas because no method had yet been devised to accurately

solve the so - precise time measurement. If British admiral Shovell had been able to rely on precise time measurement and

have run aground off the Scilly Islands in 1707. One of the worst maritime disasters in the history of seafaring, which cost the lives of 1,900 seamen, could have been prevented. For this reason, the English crown offered a prize valued at 20,000 pounds sterling to anyone who could invent a measuring process that would make it possible to precisely determine longitude. The method that seemed most likely to succeed was mechanical one: it involved measuring the

and the current time on board. Knowing the difference between these two values enabled the navigator to calculate the correct longitude for the

His legendary for precision timekeeping, it also inaugurated a new chapter in the history of modern seafaring. The H4 experienced extreme temperature variations and rough seas, yet lost a mere five seconds on an 81-day voyage from England to Jamaica. In ensuing years, more mature constructions and less costly production methods enabled England to attain nearly unrivaled preeminence in chronometer manufacturing. Famous English mariners such as Captain James Cook partly owe their fame to exact time measurement aboard their

Due to intrigues and arrogance on the part of renowned scientists, the man whom England owed its gratitude and who had devoted his entire life to the cause of exact time measurement, had to wait for quite some time until he received the promised prize of 20,000 pounds in its entirety.

1905 - 2012

More than One Hundred Years of Wempe Chronometerwerke, Hamburg.

Not only the gateway to the world, but

also the gateway to trailblazing horological

craftsmanship.

Chronometry in imperial Germany acquired international importance much later than it did in England or France. German chronometry was particularly crucial in Hamburg for two reasons: firstly, because Bremen and Hamburg were becoming increasingly important commercial centers; secondly, because Hanseatic ship-owners wanted to become independent of foreign (and especial ly English) chronometer suppliers. A number of leading German ship-owners joined together in 1905 to found the Chronometerwerke GmbH in Hamburg. This enterprise was renamed Wempe Chronometerwerke in 1938. The goal was to develop mechanized methods for manufacturing highly precise marine chronometers

an internationally competitive chronometer- manufacturing business.

the unified chronometer.

How it all started.

Wempe Chronometerwerke faced new political and economic challenges in the years prior to the Second World War and during the early years of the conflict. The business was stripped of its independence and subordinated to the ministries of the navy and air force in 1939. The sharp increase in the demand for precision instruments for warships and submarines impelled both ministries to order ever-greater numbers of chronometers from Wempe, where production was correspondingly increased. Demand was so strong that Wempe Chronometerwerke was ultimately unable to keep pace without sacrificing the quality of their precision instruments. When the ministries also asked for the speedy development of a precise yet simultaneously inexpensive unified chronometer, a cooperative arrangement was founded between Wempe Chronometerwerke and its former competitor, A. Lange & Söhne in Glashütte. Close collaboration between the two firms, along with their sharing of know-how and resources enabled them to manufacture all of the components needed for the unified chronometer. Wempe Chronometerwerke had already patented its newly developed three-pillar chronometer caliber at this time, so the Lange chronometer was adapted to match the Wempe Chronometer. Production of a unified chronometer commenced in 1942.

Together with the sextant they enabled seafarers to determine their exact position at sea. The seafaring nations invested a lot of money in the development of these precision instruments, because those who would be able to determine their position at sea would rule the Seven Seas. With his H1 terminated in 1735, a simple English carpenter named John Harrison (born 1693) became the first person to build a chronometer with a rate accuracy nearly accomplishing the performance required by the BOARD OF LONGITUDE. A test voyage aboard the ship CENTURION from Spithead to Lisbon in May 1736 however did not yet satisfy Harrison. It turned out some time later that the tables that were used to check the clock contained errors. Harrison was able to convince King George III with the H5 (copy of the H4) in 1771 and finally received the promised prize of approx. 20,000 pounds in 1773. With the development of quartz technology in the

momentary position, a captain merely needs to glance at the display of his satellite-supported global positioning system (GPS). Although traditional methods of nautical astronomy are still taught at seafaring academies, many officers feel that the use of a sextant has become more of a quaint hobby than a navigational necessity. The chronometer, which is the second important instrument for mariners, remains an outstanding horological achievement, but nowadays it is more likely to serve as a traditional decorative element with a twofold use: it shows the time and simultaneously also shows something about the character of its owner. The speedy technical progress of the 1970s seemed to have severed the cable that had anchored the chronometer to the past. But Wempe Chronometerwerke refused to abandon its devotion to seafaring and began developing electronic timekeeping systems. They also remain committed to their origins and therefore still produce exactly as watchmakers clock (type number 20004) is an enormously large and heavy masterpiece that transmits electronic impulses via a network of cables to its secondary clocks, thus assuring the synchrony of all timepieces aboard a vessel. The demands made on a clock system have become significantly more complex nowadays. GPS-synchronized clock systems guarantee a highly precise reference time, which assures uniform time display not only on all attached timepieces, but also throughout computer networks. To celebrate the 100th anniversary of the founding of the Chronometerwerke Hamburg in 2005, Wempe began developing a new generation of Wempe main clocks. After three years of developmental work, the most powerful main clock that Wempe had ever built debuted in September 2008. Specified by type number 20100, this main clock not only provides a uniform time interfaces, it also synchronizes networks and IT applications via an integrated NTP server. Last but not least, the outstanding status of Wempe Chronometerwerke Hamburg is further affirmed by the fact that all German research vessels and official ships, as well as luxury cruisers from all well-known ship lines (such as the MS EUROPA, MS DEUTSCHALND, QUEEN VICTORIA and all fifteen ships of the Holland America Line Inc.) rely on

timekeeping technology from Wempe.

Wempe ETHERNET master clock Pro type 20101 and Ethernet secondary clocks

The Master clock 20101 controls analogue and digital secondary clocks. The analogue clocks can be connected to the four available secondary clock lines. The digital clocks can be connected to the two available serial interfaces. A pulse is generated every second on the analogue lines for the control of the analogue clocks. The current time is transmitted to the digital clocks via a serial protocol. The system supports various serial protocols. In addition to the directly connected secondary clocks, the Master clock can also control secondary clocks that are connected to the Master clock via a network connection. Such a secondary clock is connected to the Master clock via a so-called Ethernet Secondary Clocks Interface (ENI). One ENI can control exactly one analogue and (or) one digital clock. The voltage supply of the ENI is provided by Power over Ethernet (PoE) so that no additional voltage supply is necessary or via stabilised 24V DC. The Master clock is configured by means of a separate operating monitor (BEMO) or a web interface. It is also possible to connect a second BEMO in order to configure the Master clock as well from another room. Furthermore the Master clock provides an NTP Server on the Ethernet making it possible to synchronize the time of LAN computers. A high-precision, quartz-controlled oscillator with an average rate accuracy of ± 0.05 s / 24 h provides the control pulse for the

its receiver signal provides the control pulse. When travelling through different time zone, the LT of the Master clock has to be adjusted manually. Analogue secondary clocks are readjusted automatically after the pre-set interval. Digital secondary clocks adopt the modified LT without time delay.

WEMPE NTP-Server

The NTP-Server provides a service for time Synchronisation on the Ethernet. Unlike usual time protocols the Local Time Server does not emit UTC, but LT. The server itself gets its time from a main clock that provides the time format LT or the difference to UTC. The server is intended to be connected to a HU20097 main clock or as an extension for the UTC-related NTP of the HU20100 main clock. Connected computers can thus get the current local time set on the main clock from the Local Time Server via NTP service. The server is connected to the main clock by means of a serial interface. After the server has been put into

operation or following a Power-UP, a programme starts running on the server that analyses and further processes the time protocol. The system supports two main clock protocols (itron und itron2000). As delivered, the Local Time Server tries to retrieve its IP address assignment dynamically (DHCP). It is however recommended to assign a static IP address to the Local Time Server.

WEMPE marine clocks

WEMPE marine clocks are specially designed to meet the needs on board a ship. They stand out due to their state of the art technology and their functional and compact design. Furthermore, they are durable, easy to mount and to operate and only need minimal Maintenance. Our standard programme includes special built-in secondary clocks of 96x96mm and 144x144mm in different versions, prestigious high quality wall clocks as well as clocks for every location aboard a ship. Being an exclusive licensee of the MOBALine Technology, we are able to offer you secondary clocks that can be installed and put into operation in a considerably reduced time. The MOBALine Technology works on the basis of an intelligent secondary movement that adjusts itself automatically to the correct time once it has been connected to the MOBALine System controlled by the Master clock. The usual setting of the time by hand is hence not necessary anymore, which is also of great advantage after a power failure and service.

Precise, durable and state-of-the-art clock movement technology!

1.5V battery-powered quartz clocks Type B

The accuracy of quartz movements is provided by a quartz oscillator (frequency 32.768 KHz). A possible deviation of rate would be less than 1 second per day. Analogue quartz clocks have to be set and adjusted manually to the current time. Analogue quartz clocks run on standard batteries. Advantages: Sturdy and durable movement Masters-independent power supply Interference-resistant Most economically priced movement type

quartz clocks for 24 VDC Type Q / QZV

These clocks do not run on standard batteries as usual for quartz movements, but Masters power supply. This does not at all affect

their accuracy. Advantages: Sturdy and durable movement No battery change necessary Economically priced movement type

Analogue secondary clocks, 12-24V DC minute impulse Type T:

Secondary clocks are always controlled by a Master clock. The switchable 12 24V DC alternate polarity minute impulse is transmitted via a 2 or 4-core wire (secondary clock line). All secondary clocks are connected in parallel to the secondary clock line or via junction boxes. The minute impulse is at the same time the operating voltage of the analogue clocks. The total power consumption of all secondary clocks, which may not exceed the total output power of the Master clock, results from the number of connected secondary clocks, the cable length and the wire diameter. The advantage of secondary clocks is that all these clocks display an identical, uniform time since they are all controlled by the same Master clock. If the Master clock is equipped with a GPS module the system is always synchronised to the most precise time. Secondary clocks with a minute impulse movement do not have a second hand. If the Master clock is fitted with batteries for power supply backup, all connected analogue clocks will stop running in case of blackout, but they adjust automatically to the correct time once the Masters supply is back again. Advantages: Stable, reliable and time-tested clock technology Sturdy and very durable Uniform time display Cost-effective clock technology

Analogue secondary clocks, minute and second impulse 12-24V DC Type T: To control secondary clocks with a minute and second impulse movement it is necessary to have a Master clock featuring at least two secondary clock outputs/secondary clock lines, i.e. one for the minute impulse and one for the second impulse. Minute and second impulse secondary clocks are driven via a 4-core wire. Advantages: As for the a.m. secondary clocks with minute impulse, but additionally with second hand.

Maintenance-free thanks to self-setting! No re-setting problems for clocks with difficult access. Battery change not necessary. Power supply of secondary clocks through the MOBALine. Use of already installed 2-wire lines, low voltage.

Ethernet secondary clocks Type IP

The Ethernet data switch/hub directly supplies the Ethernet secondary clocks with the necessary operating voltage via PoE (Power over Ethernet). Every secondary clock is equipped with a small µC. The Ethernet segment provides UTC and Local Time as time information. Each secondary clock module saves the actual position of the hands and determines automatically the difference between that time and the current system time. In case of a power-down, the current position of the hands is stored (non-volatile storage) so that the clocks show automatically the current time once the system has been rebooted. A special broadcast address facilitates the data exchange with the Master clock so that any requested number of clocks can be fed by the Master clock. Master advantages of the Ethernet secondary clocks:

Easy to put into operation: secondary clocks automatically log on the system via DHCP.
