Maurice Lacroix Masterpiece Calendrier Rétrograde Ref. 51717

A symbol of classic Swiss watchmaking fused with modern innovation, the Maurice Lacroix Masterpiece Calendrier Rétrograde Ref. 51717 showcases the brand’s renowned technical creativity and refined aesthetics. This exceptional timepiece combines traditional mechanical craftsmanship with a distinctive dial layout that is both harmonious and intellectually engaging.

Encased in stainless steel (approx. 43 mm diameter), the Calendrier Rétrograde exudes elegance and balance. Its silvered guilloché dial features a unique interplay of textures and levels, giving depth and character to the display. The retrograde date arcs gracefully across the lower left sector, while a power reserve indicator rests at 12 o’clock and a small seconds counter at 3 o’clock ensures perfect visual symmetry. The blued feuille-style hands contrast beautifully with the silver dial, enhancing legibility and refinement.

Every detail — from the domed sapphire crystal to the finely fluted crown — speaks of careful design and the horological precision typical of Maurice Lacroix’s Masterpiece series.
