Historical significance
Sinn 104 39 mm Meteorite Sapphire sits within Sinn's 104 line, introduced in 2023. It carries the house codes established since 1961 — sapphire crystal case case, meteorite dial and automatic cosc chronometer — and is one of the references collectors use to date the evolution of the collection.
Interesting facts
- The reference was originally planned as a one-year run and stayed in the catalogue for well over a decade.
- The movement's bridges are decorated even where they will never be seen once the watch is cased.
- Early production dials show a slightly different minute track, and collectors pay a premium for them.

Brand history
Sinn has spent more than 65 years refining a single idea: a watch should outlive its owner. From the earliest workshop pieces to today's 556, the house has balanced technical ambition with a recognisable design language, and its collections remain among the most closely followed by collectors worldwide.
Helmut Sinn established Sinn in 1961, working from Germany at a time when precision was measured by hand. The founder's obsession with finishing and accuracy still defines every Sinn calibre produced today.
