Omega R17.8 Chronometer (1942)

£ 1,500

This is an extremely rare Omega manual wind chronometer dating from spring 1942. The movement of this watch is unusual - normally Omega concentrated on producing chronometer using the 30T2 movement. Omega produced a very small number of these movements which were regulated to achieve chronometer performance (that is a deviation under test conditions of no more than a few seconds gain or loss per day).

One can only speculate about the reasons Omega regulated these smaller movements - perhaps it was simply a technical exercise to show that any of their movements could be regulated to a very high standard, or perhaps they were hedging their bets that smaller, tonneau shaped watches would come back into fashion as they had done in the 1920s and 30s.

An extract from Omega's archives is included as part of this - the extract states that the watch was originally delivered with a "Bulletin Du Marche" that is a certificate showing it had passed the chronometer tests.

The stainless steel case is a small size at 30mm, although presumably intended as a man's watch. It has a screw-back to significantly improve the water resistance. The dial has a nice, even patina where the varnish has degraded, but not significant losses to the printing.

The watch has been fully serviced and regulated and performance is now very good. It comes with a nos Omega strap and buckle.

Shipping guide for t-shirts

All t-shirts on our website are now printed and shipped by an external supplier inside the UK. This means that if you place an order for both a watch and a t-shirt, they will be shipped separately.

Our supplier uses a Royal Mail tracked service for all shipments and this usually takes a little longer than our watches. You can see an estimated timescale when you input your address at the checkout.


Please note, during busy sale periods dispatch may take a little longer (this is quite rare). These delivery times are a guide based on the carriers terms of service, products may, in some unusual cases take longer to arrive. If this happens, please get in touch.
