For those keeping score, I now have a Tradition Tourbillon 7047, a Classique Hora Mundi 5717, and now a Classique Musicale 7800. There's one more Breguet (the Classique Chronometrie 7727) on my list before I feel my collection is complete, but I'm feeling good for now.

I met @MDT on this site when I posted about my Breguet 7047, and we met up in real life at Geneva Watch Days. We were talking about our wish lists, and I mentioned that I'd been looking for a 7800 Bach version with the box. I'd been looking for a few months when MDT told me he that he saw one come up for sale in a FB group he's in. I reached out, and the rest is history! So thank you again MDT!

Here's a pic of the front:



And here is the epic box. It may be even more epic than the super epic 7047 box!



Breguet made an exception to their coin edges for this model:


The gang's all here!


Of course to show off the watch properly, I'd need to post a video. I don't think I can upload a video directly here and I'm not sure I want to post one to YT yet out of concerns for doxxing myself. But if you're not familiar with this watch, do yourself a favor and watch some YT videos about it, both the Bach and Rossini versions. I preferred the Bach, but I'm probably in the minority on that.

About the Breguet Tradition GMT Ref. 7800

The Breguet Classique Musicale reference 7800 is a highly complex timepiece that integrates a musical mechanism capable of playing a melody on demand. This model stands out within the Classique collection for its innovative approach to horological complications, moving beyond traditional timekeeping functions to incorporate an auditory experience. It represents Breguet's continued commitment to intricate mechanical artistry and the development of novel complications. The musical mechanism is activated by a pusher, allowing the wearer to enjoy a pre-programmed tune.

The 7800 features an 18k rose gold case with a diameter of 40 mm, housing the manual-winding caliber 507TMG. This movement is visible through a sapphire crystal caseback, showcasing its intricate construction and the components responsible for both timekeeping and the musical function. The watch offers a power reserve of 50 hours and is water-resistant to 30 meters. The dial is silver, often featuring a hand-guilloché pattern, and is protected by a sapphire crystal.

This reference appeals to collectors who appreciate Breguet's high-complication pieces and those interested in watches that offer unique interactive features. The Classique Musicale 7800 is part of a lineage of Breguet watches that push the boundaries of mechanical innovation, sitting alongside other notable complications in the brand's contemporary catalog. Specific variants exist, such as the "Bach" version, which plays a melody composed by Johann Sebastian Bach, adding a layer of thematic interest for collectors.

I almost bought the same one posted there. It was a GREAT deal. I'm honestly shocked Breguet is still as well priced as it is on secondary. A huge horological value for a reasonable price...which seems increasingly rare nowadays. Congrats on the pick up. Excellent excellent piece!!!

Not the average Breguet collection, all 3 are pretty special and very big for this brand, your last one is just huge I handled it a few times, really nice but very big I could wear them cause I’m used to big watches and I would love to wear all 3 of them 😀
