Hermès H1912

Probable

The third Vaucher-built Hermès caliber in this catalog alongside the H1837 and the ultra-thin H1950, and — like the H1837 — named for a year rather than a series. Its practical significance is that it powers only part of the Cape Cod line: the TGM size is the mechanical one, and the smaller sizes are quartz.
