H1 Chronometer is a wristwatch from Hentschel.

Timeless classic with clear, uncluttered dial, finely contoured leaf hands and elegantly shaped case in red or white gold or stainless steel. There are two case sizes: with 37.0 or 39.5 mm diameter.

Each movement in this series is tested for 1,000 hours in six positions and finely regulated. The chronometer certification is carried out according to the strict criteria of the former Deutsche Seewarte in Hamburg, where certification had been taking place since 1877.
