i have been searching for a panda for a while
I can't talk too much about the history of it given my relative inexperience on the topic, but if you're seeking thoughts on whether to buy or not, looks pretty good to me. Particularly as you say that you've been looking for similar for a while. If the price is in budget, and provenance, seller's credentials and paperwork all check out then go for it.
Hi Luzer- nice find.
This watch has a 30-minute register, making it a Carrera 30 rather than a Carrera 45 (Ref. 3647 is a Carrera 45). The reference on this watch is likely Ref. 7753 NT.
"Fab Suisse" on the dial marks this out as a French-market watch. The French has a rule banning imports of any products that could be confused for being French but weren't. To make sure there was no confusion, Swiss watchmakers added "Fab Suisse" ("Fabrique en Suisse"- "Made in Switzerland") to the dials of watches bound for France.
The watch should have a Valjoux 7730 movement- perhaps ask the seller if there are any photos of the movement.
In short, the watch looks to be in great condition, although not possible to tell if the case is original or has been polished.
Nice panda dial, so I take it the 7753 based model replaced the earlier V92 models?
The 7753 uses the Valjoux 7730 (in Heuer code, "53" is Carrera, so Ref. 1153 is a Calibre 11/ 12 Carrera. They didn't change the codes when the moved to the Calibre 12. "33" is Monaco, so 1133B is the Blue Monaco Calibre 11/ 12). These codes changed over time, so the early V.72 Carrera is not the 7253, but the 2447!
7730 is a development of the old Venus 188 from the 1940s. Think that it's a lower-cost movement than the V. 72.
