Description

This rare Chronosport by Helmut Sinn Regattatimer features a Lemania cal.5270 mechanical movement with 17 jewels, essentially a hand-wound version of the cal.5100. The stainless steel case measures 38mm in diameter and 14mm in thickness, with a distinctive blue dial and mineral glass crystal.

Key features:

• Mechanical manual-wind Lemania 5270 movement (No.04263615)
• Regatta timer function with date display at 6 o'clock
• Stainless steel case and bracelet (B&M style, fits up to 19cm wrist)
• Blue dial with good legibility for timing functions

The watch is in working condition and keeps good time, though absolute accuracy hasn't been tested. It shows slight to visible signs of wear consistent with its second-hand status, making it a characterful vintage piece. The mineral glass remains in good condition. Perfect for collectors seeking a functional regatta timer with Swiss heritage.
