Sieko Santos Mod

Classic elegance reimagined — our Custom Seiko Santos Mod pays tribute to the iconic square-case design of Cartier’s legendary Santos, blending timeless sophistication with the reliability of Japanese engineering. At its heart beats the Seiko NH35 automatic movement, a workhorse caliber known for its durability, accuracy, and smooth sweep of the second hand — no batteries required.

The 40mm 316L stainless steel case features the instantly recognizable squared profile with exposed bezel screws, finely brushed and polished for a refined finish. A flat sapphire crystal protects the dial, while bold Roman numeral markers and luminous hands ensure readability in any setting. The slim, integrated case design offers both comfort and elegance on the wrist.

Choose between the integrated stainless steel bracelet for a true Santos aesthetic or a premium leather strap for a more classic, dress-oriented look. Whether paired with formal attire or worn casually, this mod delivers a statement of style at a fraction of the luxury price.
