Hoseachandra's journey to acquire a yellow gold dress watch culminates in a detailed review of the Breguet Heritage ref. 3670. His personal quest highlights the enduring appeal of specific aesthetic and mechanical preferences within luxury watch collecting. This article explores why this particular Breguet reference stands out for its unique design and robust movement, offering valuable insights for collectors considering less common, yet historically significant, timepieces.
Since i started this hobby, i've always wanted a yellow gold watch. In fact, my first expensive watch was a Yellow gold plated Montblanc Star, with breguet numbers...a very handsome watch. But it was a quartz, so when i began to admire mechanical watches , i sold it.
Few years after that, i bought a Yellow gold Cartier Tank Solo...a solid gold watch...that was a progress...but still a quartz.
Then in 2017 i bought A rose gold Cartier Tank Louis Cartier with mechanical movement. A very lovely watch and until today, still my most expensive watch. Again, my heart still looked for Yellow gold. So i gave the Tank to my wife (occasionally i still wear it, because its just a very refined and beautiful piece).
After 7 years, last week i finnaly found my dream : A (preowned) Breguet Heritage ref 3670 in yellow gold. Automatic caliber 532 (Lemania 1352-based), no date, perfect size at 34 x 42 mm. Curved case, curved glass, curved caseback, sits very comfortably on my wrist.
I had considered Breguet clasique ref 5920, but decided that the tonneau case of 3670 is more unique and rare, and i have too many round watches. Also a first generation of Marine was available, but after some research i found that it use JLC cal 889, which more delicate than Lemania caliber.
Since this acquisition, i become smitten by Breguet, and looking forward to get the newest Marine in rose gold. I think Breguet is a gem in a watch world, without hype, celebrities ad, silly game with AD, etc. And i hope it stay that way.

A true curved watch. This is all the curved watch should made, not with flat caseback.

Notice the different guilloche on the main center and the subdial
About the Breguet Classique Ref. 3670
The Breguet Heritage 3670 is a distinctive tonneau-shaped timepiece that stands out within the brand's collection, which is more commonly associated with round cases. This reference showcases Breguet's ability to adapt its classical design language, including the signature Breguet numerals and blued hands, to a curvilinear form. It represents a period in Breguet's history where it explored various case geometries while maintaining its commitment to traditional watchmaking aesthetics and craftsmanship.
This particular reference features an 18k yellow gold case measuring 36 mm, housing an automatic movement, the Caliber 502.3. The movement provides a power reserve of 45 hours. A sapphire crystal protects the silver dial, which is adorned with the characteristic Breguet numerals. The watch is water-resistant to 30 meters, indicating its design for dress wear rather than aquatic activities.

Its tonneau shape provides an alternative aesthetic for those who appreciate historical design elements combined with a less common case form. This reference contributes to the diversity of Breguet's offerings from the mid-1990s onwards.
