Precision in rectangular form is rarely executed this cleanly. The 5124G-001 is built in a 43 x 33.4 mm white gold case with stepped Art Deco architecture that emphasizes linear balance. Its vertically brushed dial carries applied markers and stylized numerals, while blued steel hands add contrast. Inside, the manually wound Caliber 25-21 REC PS operates at 28,800 vibrations per hour with approximately 44 hours of power reserve, specifically engineered to match the case proportions.

What sets this reference apart is not just its shape, but its discipline. Every line, every proportion, every mechanical component aligns with a singular design philosophy. It is a watch for collectors who understand structure, not just aesthetics.
