The Breguet 5817 Marine is a watch that I have desired for quite a while. Its flitted about near the top of my wishlist for a few years now and I recently got the chance to pick one up on the secondary market for an excellent price. The watch, an early model from 2004, is itself is in very good condition with mostly the expected hairline scratches on the case. The clasp on the other hand has some rather more noticeable scratches but that doesn’t bother me.


I’ve now had the watch for about 3 weeks and so I’ll try to put across some thoughts though mostly this is about the pictures

The Marine has a 39mm stainless steel case which may surprise some as it wears larger than that figure might suggest. Key to this are the rather large and aggressive lugs.


The overall design of the watch combines cues from classical Breguet dress watches with more sporting elements. For some people the effect is neither here nor there. However, fans of this watch such as myself find it to be a superb combination that creates a casual sports watch appropriate for daily wear but with a great deal of flexibility. I think smart casual is an ideal word to describe the watch on bracelet or rubber although on a leather strap it could easily be taken for a purpose built dress watch. In usage situations it probably overlaps the most with my 116520 Daytona.


I have always loved the detailing on Breguet cases and the Marine does not disappoint. The case is polished on all surfaces and features a double stepped bezel. The sides are fluted in the traditional Breguet fashion. It should be noted that the fluting is created by cold rolling onto the case before finishing by hand.


The crown screw in crown is signed with the B from the logo and protected by two interesting curved crown guards. The watch is rated to 100m of water resistance.


The crystal is uncoated but slightly domed which helps reduce reflections somewhat. It tops off the watch at a reasonable 11.82mm thickness.











The previous owner had it on a dark brown leather strap which did not suit the watch at all IMO. I switched it to the original black rubber strap (which was included). I think I will try to get the navy blue rubber strap which was originally made for the blue dial version as the dark blue should be a nice complement to the blued steel hands and markers


The strap is secured with a deployant clasp which itself is adjusted with an oversized tang and buckle and two large steel loops. Again I suspect this will evoke mixed feelings but I quite like it.


As with other Breguet watches the strap is held by a screwed bar instead of a spring bar. It’s secure yes, but a pain to change straps it looks like. It took the dealer a good few minutes to switch the strap from the leather to rubber (although that included changing over the buckle hardware as well). If that were not the case I might consider the bracelet as option.


The lugs are welded onto the case and are quite large. However since they are shaped to fit the wrist, it is not a problem for me. On the wrist, it wears extremely comfortably and is a good fit for my 6.7inch wrists.








And now on to the star feature of the watch… the dial. Breguet’s dials are made of solid gold and engine turned by hand on a rose lathe before being silvered.


Unlike most Breguet watches which utilise a few different guilloche pattern, the 5817 features only one. However this one pattern is a beautiful and mesmerising wavy spiral that plays with the light in many interesting ways. I am not kidding when I saw that I am regularly distracted by the dial when I am wearing this watch as I catch myself just staring and moving it around in the light


The chapter ring is stepped and detailed with circular brushing. The hour markers are applied Roman numerals and heat blued. The minute markers are on an outer track and include subtle luminous markers on the hours.


The hands are of course open tipped Breguet hands, a signature so closely associated with the brand that it’s on the logo not to mention that even other watchmakers refer to them as such. In the case of the Marine, the open tips are actually filled with lume and are of course heat blued to match the hour numerals.


The big date is integrated into the chapter ring very nicely. The windows are nicely detailed and its placement means it does not disrupt the beauty of the centre of the dial. Thus the date is both highly legible and out of the way when not needed. The switchover is instantaneous at midnight.
