France Ébauches FE 7121

Probable

The movement of the original 1982 JB200, and the single most useful fact about that watch: it is a quartz diver, not a mechanical one. Buyers approaching it as a vintage Swiss automatic — and listings that present it that way — have the watch wrong before any question of authenticity arises. A one-second-per-tick seconds hand on a 1982 JB200 is correct.

Architecture

French quartz caliber of the early 1980s with centre seconds and a date.

Service practice

France Ébauches ceased production and parts for its quartz calibers are scarce. A forty-year-old French quartz movement that has failed may be genuinely unrepairable, and a replacement of a different caliber is a common and often necessary outcome — an originality finding to record rather than a defect to condemn.
