This Oris BC3 (BC for Big Crown) is a rarer watch from their range.  Model reference 635-7514


While we do not have the papers for this watch we have found BC3 examples from between 2002 and 2004.  As this watch has the red rotor, which came in on all Oris automatic watches in 2003, we are pretty sure that circa 2003 will be quite close.


This is a substantial divers watch and feels very well put together.  With a lot of divers watches too much is dedicated to the 200M water rating, whereas this has lots of details.  The dial is two tone, looking different in different lights and never being boring.  Having the day and date showing on the centre line of the watch adds nice symmetry to the design.  The 120 click bezel is one of the most positive we have experienced, and the clous de Paris edge is well executed and practical – even wearing diving gloves grip would not be an issue.  The movement is designated Oris 635, but it is heavily based on the popular and reliable ETA 2824-2.  This 25 jewel calibre has quick set day and date, and hacking, all operated via the signed screw down crown.  The case is all pretty good, with just slight marks on the lugs from strap changes.  The bracelet is quite long and our sister website,, may have extra links if required. The bracelet has been cleaned in our ultrasonic bath, and has the divers fliplock extension to go over the top of wetsuits.

This watch will be supplied with our branded presentation box and our Certificate of Authenticity.
