Historical significance
Louis Moinet Impulsion 43 mm Skeletonised Sapphire sits within Louis Moinet's Impulsion line, introduced in 1992. It carries the house codes established since 1806 — sapphire crystal case case, skeletonised 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.

Brand history
Louis Moinet has spent more than 220 years refining a single idea: a watch should outlive its owner. From the earliest workshop pieces to today's Memoris, the house has balanced technical ambition with a recognisable design language, and its collections remain among the most closely followed by collectors worldwide.
Louis Moinet established Louis Moinet in 1806, working from Switzerland at a time when precision was measured by hand. The founder's obsession with finishing and accuracy still defines every Louis Moinet calibre produced today.
