Omega MEGAQUARTZ 4.19 MHz ship’s marine chronometer

A beautiful quartz chronometer, from an Omega project which dates back to 1978. This clock (reference PE5806) dates 1983. The original clocks were produced for the French navy – and were the most accurate timepieces available (apart from an atomic clock). The design performance of the calibre 1525 movement was to give an accuracy of less than 5 seconds per year – and indeed there is a problem finding a suitable timepiece to check the accuracy of this clock.

The power supply is two standard 1.5V AA batteries. When changing the batteries they can be exchanged one-at-a-time, so that the clock does not have to stop. A set of batteries provides power for between 2 to 3 years.

A description can be found in Wikipedia: https://en.wikipedia.org/wiki/Omega_Marine_Chronometer

It is also to be found in AJTT p.203 (PM me if you don’t have a copy).

In addition to being a clock for the French navy, they were later made available commercially – and were sometimes used as presentation pieces by embassies. It is recorded that it was chosen by the City of Geneva for presentation to the Presidents Reagan and Gorbachev during the America-Russian summit in 1985.

Provided with the clock is its Neuchatel Observatory Bulletin dated 1983, showing the number (1285) which also appears on a brass plaque on the front of the clock.

The clock is mounted in a beautiful mahogany case with a hinged lid and brass fittings – including brassed corners. The base of the mahogany case is velvet – and there is an angled wooden base (also with velvet) on which the case can stand, without sliding.

The clock is mounted on a brushed aluminium base which is hinged to allow access to the batteries and the setting/calibrating controls.

For further details or images, please send me a PM.

The clock is in full working order and in beautiful condition.

One of the most accurate timepieces in the world could be sitting on your desk!

That is sick.

As I wrote in my description, the problem is choosing a suitable time source for monitoring the accuracy - internet clocks are certainly not of use. Although it is easy enough to calibrate it - I never need to make a change.

Still for sale! Keen to sell.

Giving this a bump because I’d like to help it find a new home. I seriously considered it but it’s just not right for me. I still think it’s a gorgeous thing, though.
