Designer
Gérald Genta
Gérald Genta (1931–2011) trained as a goldsmith in Geneva and became the most influential watch designer of the 20th century. Working freelance, he sketched the Audemars Piguet Royal Oak overnight in 1970, followed by the Patek Philippe Nautilus, the IWC Ingenieur SL and the Bulgari Bulgari — defining the integrated-bracelet luxury sports watch as a category.
Historical significance
H. Moser & Cie. Streamliner 42 mm Black Grade sits within H. Moser & Cie.'s Streamliner line, introduced in 2007. It carries the house codes established since 1828 — grade 5 titanium case, black lacquer dial and micro-rotor automatic — and is one of the references collectors use to date the evolution of the collection.
Interesting facts
- 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.
- The reference was originally planned as a one-year run and stayed in the catalogue for well over a decade.

Brand history
H. Moser & Cie. has spent more than 198 years refining a single idea: a watch should outlive its owner. From the earliest workshop pieces to today's Streamliner, the house has balanced technical ambition with a recognisable design language, and its collections remain among the most closely followed by collectors worldwide.
Heinrich Moser established H. Moser & Cie. in 1828, working from Switzerland at a time when precision was measured by hand. The founder's obsession with finishing and accuracy still defines every H. Moser & Cie. calibre produced today.
