Le Coultre Rectangle Moonphase Watch

W103
This extremely rare Le Coultre rectangular wristwatch dates from the 1930's. It features a complicated tonneau nickel lever movement, mono-metallic compensation balance, 17 jewels, silvered matte dial, sub dial combining seconds and phases of the moon, windows for months and days of the week, and an outer ring calibrated for date. Chased with engraved hour indexes, the gold filled case is signed as are the dial and movement.

The seven functions of time that this watch performs mechanically in such a small (37.0 millimeter diameter) case are astounding considering that it was hand crafted over 60 years ago! In good working condition, this is a superb timepiece for the serious collector.
