Details
A Golden Age Of Mechanical Ambition
In 1990, Breguet launched the modern Marine collection, reviving a legacy that began in 1815 when its founder was named Chronometer-Maker to the French Royal Navy. The watches from this initial 1990s period are a study in confident, classical watchmaking. This reference 3700BA "Hora Mundi" is a prime example, housing a genuinely complex world time complication inside a solid 18K yellow gold case. It represents a moment when Breguet reasserted its identity as a top-tier house by building mechanically ambitious watches that were meant to be worn, not just admired. This was not a brand chasing trends, but one leaning into its own two centuries of horological authority.
A World Of Detail, Controlled From The Crown
The brilliance of this watch is in its execution. The dial is a multi-layered world map, a backdrop for the classic Pontiffe hands that are signatures of the house. Yet, the complexity is managed with ingenious simplicity. The crown is a dual-function system, allowing the wearer to change the world time city disc with one section and adjust the local time and date with the other. This level of sophisticated engineering, which few brands attempted at the time, is the true substance behind the Breguet name. It is a highly functional complication presented with classical grace.
Excellent And Unmistakably Breguet
This 1990s example is in excellent physical condition. The 18K yellow gold case retains its sharp lines. The intricate Hora Mundi dial is clean and well-preserved, showcasing the fine details of its construction. The watch is fitted to its original leather strap and correct 18K yellow gold Breguet buckle. As with every watch we offer, this piece has been verified as mechanically sound and is ready to wear.
For The Collector Who Needs No Introduction
A gold Breguet Marine is an unusual and deeply satisfying proposition. It delivers the history of the oldest name in watchmaking, a genuinely useful high complication, and a design language that is entirely its own. This is not a hype watch. It is for the collector who understands the difference between passing trends and permanent significance, and who has no interest in explaining their choice to anyone. It is a piece of serious watchmaking with an unimpeachable pedigree.

What Our Clients Say About Us

I knew I was gonna like Danny, based on his name, but nothing could’ve prepared me for how great of an experience this was. He had the most beautiful 70s Seamaster Cosmic on his website and I was set to be married 2 days later - I arranged to buy it but before leaving we both realized it needed to be serviced. I panicked, because I was literally buying this for my wedding, and Danny being the legend he is, loaned me a nearly identical Seamaster to make sure I could get through the event Never have I had someone go so above and beyond for me, especially while purchasing one of the lesser priced items in their inventory. He serviced my watch and exchanged it with me after the wedding on a super fast turnaround timeline. I would sincerely recommend you visit this guy, you will not be disappointed Edit: adding a pic of the loaner (two tone) and the owner (crosshair)

Great service and shop. Danny and his team were incredibly accommodating, professional, and kind. Great selection of vintage watches. Their store is the hidden gem in the diamond district.

This was my first real luxury watch purchase, a Rolex 15200 Date 34mm, I own Tissots and a Laco, but those are entry level luxury watches. I found Danny’s Vintage Watches online, and had great feedback both on Google, Chrono24 and the Reddit watch community. So decided to give him a shot as buying online can be a crap shoot. Ordered Monday night, was at my doorstep Friday morning. Despite the watch being over 30 years old, serial number says it’s from 91, the watch looked new. Didn’t come with box or papers, and was shipped in a plastic sleeve wrapped in bubble wrap. Danny was always available to answer questions. I’ll be buying from Danny again for the next purchase…saw a couple of Speedmasters on his site I liked….
