About this product
Slate with diamond markers under a domed diamond-set Everose bezel. The domed setting curves the stones around the bezel's profile rather than presenting them flat, and it is the less costly of the two diamond bezels on this case. Cool grey refusing the warmth of the rose gold. On the Jubilee bracelet in 31mm. Calibre 2236 runs at roughly fifty-five hours with a silicon Syloxi hairspring.
This watch comes with the manufacturer's warranty card, backed up by our own Alan Furman & Co warranty.
