The SL325 Automatic Mechanical Watch redefines open-worked design within a bold, sharp square silhouette. Sculpted entirely from hardened K9 glass across its case, flat crystal, and crown, it introduces a completely translucent, 360-degree exhibition space on the wrist. Inside, a dependable Tianjin Seagull automatic caliber operates a center 3-hand configuration, perfectly integrated with an active kinetic flywheel window at the 6:30 position. Paired with an ultra-flexible liquid silicone strap, it delivers an understated, weightless architectural presence.
