Slim, proportioned, and instantly recognizable, this reference is built around a 40mm stainless steel case with a horizontally embossed blue dial that shifts tone under changing light. The integrated bracelet flows seamlessly into the case, delivering both structural strength and ergonomic comfort. Powered by a self-winding mechanical caliber, the watch maintains precision while preserving a remarkably thin profile. The sapphire crystal case back reveals refined finishing, while the date aperture at 3 o’clock is cleanly integrated into the dial architecture.

Few watches achieve this level of balance between sport and refinement. The 5711/1A is not defined by complication, but by execution. It represents a standard in luxury steel watchmaking that continues to command global demand and collector respect.
