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
Hamilton Khaki Navy 41 mm Ice Sapphire sits within Hamilton's Khaki Navy line, introduced in 2020. It carries the house codes established since 1892 — sapphire crystal case case, ice blue dial and automatic powermatic 80 — and is one of the references collectors use to date the evolution of the collection.
Interesting facts
- Early production dials show a slightly different minute track, and collectors pay a premium for them.
- The bracelet tapers across its length, which is why the profile looks thinner on the wrist than the specification suggests.
- The reference was originally planned as a one-year run and stayed in the catalogue for well over a decade.

Brand history
Hamilton has spent more than 134 years refining a single idea: a watch should outlive its owner. From the earliest workshop pieces to today's Khaki Field, the house has balanced technical ambition with a recognisable design language, and its collections remain among the most closely followed by collectors worldwide.
Adam Bopst & Charles Rood established Hamilton in 1892, working from United States at a time when precision was measured by hand. The founder's obsession with finishing and accuracy still defines every Hamilton calibre produced today.
