“The 7A28 was the world’s first analog quartz chronograph, and to say they got it right is an understatement. Solid construction, “fly by wire” circuitry, and a hefty 15 jewels make for a finely tuned machine that can be adjusted to dial in performance, and allows for the replacement of worn components. Known as the “Black Bond”, as this variant is the inverse color way of the white dial version featured in the James Bond film, “A View To A Kill.” This particular example barely shows its age, with no obvious wear on the case/bezel, a flawless crystal, and some minor discoloration on the lume of the hour and minute hands. Watch functions perfectly, keeping fantastic time and all chrono functions working as expected (see video here: https://imgur.com/a/JC5c4lg) It is currently on an aftermarket jubilee, but I will include the original bracelet with signed clasp (with a couple additional links). The only reason I switched the bracelet out is due to the original having some minor gaps where it meets the case/lugs, but it is nothing egregious. Diameter- 37.5mm Lugs- 20mm Price: $450 OBO shipped w/in CONUS. Love these 7a28s to death, only selling this one because my collection has grown a bit out of control and I need to recoup some $$. . These are some of the best looking chronos ever made imo, and, despite being the first analog quartz chronograph, are commonly acknowledged as one of the better quartz movements of all time. Let me know if you have any questions, thanks for looking!
