Vintage Rotary Automatic 21 Jewels Day-Date Men’s Watch – Swiss Made –...
For sale is a vintage Rotary Automatic men’s wristwatch, Swiss-made, likely dating from the 1970s.
This piece features a blue dial, day-date display, and a stainless steel case with integrated bracelet — a classic retro design from the era.
The automatic movement is running and keeps time when wound or worn, but the stem does not engage to set the time or date, so it will require repair or adjustment.
The movement bears markings including “MD” and “7003”, consistent with the A. Schild 7003 (AS 7003) or a similar Swiss automatic calibre used by Rotary during this period. Since the exact identification cannot be confirmed without full disassembly, it is listed as “AS 7003-type” for accuracy.
