ED209 offers an insightful hands-on review of the Breguet 5377 Ultra Thin Tourbillon, a timepiece renowned for its technical prowess and elegant design. His detailed observations highlight the watch's impressive 3mm thin Calibre 581 DR and peripheral rotor system, providing a valuable perspective for collectors interested in ultra-thin complications. This article explores the nuances of its design and movement, inviting readers to appreciate Breguet's engineering achievements.









The reference 3797 represents Breguet's approach to the minute repeater complication within the Classique collection. This reference delivers the traditional chiming mechanism in a relatively compact 36mm format, positioning it as an accessible entry point into Breguet's minute repeater offerings.
The watch features an 18k yellow gold case measuring 36mm in diameter with a fixed bezel configuration. A silver dial sits beneath sapphire crystal, while the manual-winding movement provides the mechanical foundation for the minute repeater function. Water resistance extends to 30 meters, reflecting the dress watch orientation of this timepiece.
This reference appeals to collectors seeking minute repeater complications in a more wearable case size. The 36mm proportions and yellow gold construction align with traditional dress watch conventions, making the 3797 suitable for collectors who prioritize the acoustic complication over contemporary sizing trends. The silver dial provides a neutral backdrop that complements the yellow gold case material.
It's pretty amazing to see! I recall being in NY when they officially debuted the Carl Bucherer with the peripheral rotor. Thanks for the pics! -MW
And your pics do justice to the Watch, which is very Breguetesque. ;) For those who like Tourbillons, this is an interesting offer. The only thing which disturbs me on this one is the size... 42 mm on such an elegant Watch is a bit too much, and even more when it is thin like this! Best, Ed, and thanks for the good write up.

First of all, I would thank the staff of Breguet Boutique in New Bond Street. The level of service was exceeding all other brand boutiques on the same street. We got friendliness, professionalism and the so typical arrogance was totally missing. Great visit! I must agree with Nico; the watch is too larger. At 38 - 39 mm it would be much nicer. I am not a great fan of tourbillon but the watch is really nicely made and the way the oscillating weight is designed, is really clever. This 5377 is an a
Hi Nico Well time for two watchmaking definitions. First "ultra-flat". These are watches where the case is used as a functional part of the movement. Of course, this makes the watches with this construction thinner. However, ultra-flat movements have not enjoyed a reputation for reliability. There simply is too much of a chance that there will be enough flex in the caseback to affect the running of the movement (think of it: when the movement is separate from the case, it is protected from flexi
Looking forward to the report on the fusee chain... Ovi
Some of the so called Utlra Thin JLC watches. Not that they are not very nice nor uninteresting, I just consider that since a certain thickness, we cannot use this appelation " UT " other than for some marketing purposes. That doesn't remove the beauty of this Watch, though. Best, Nicolas
