L. Leroy L610SQ

The L610SQ is a hand-wound movement from the Osmior family, introduced by L. Leroy in 2025 as part of the brand's revival. It contains 321 components and delivers a 90-hour power reserve. Based on the L601SQ architecture, it omits the repeater and tourbillon complications found in higher-tier Osmior calibers, positioning it as a time-only option within the collection. The movement remains in production.
