Automatic movement and everyday functions
The 4R36 automatic movement is powered by wrist motion, giving this watch a traditional mechanical operating experience without a battery. The stated stop-second hand function can help with more precise time setting.
Day and date displays add practical information at a glance, while the silver dial and LumiBrite-treated hands and indices are designed to support readability in low-light conditions.
Case, bracelet and durability
The 42.5mm stainless steel case has a 13.4mm thickness and a 170g listed weight, so this is a watch with a deliberate, substantial wrist presence rather than a discreet profile.
The stainless steel bracelet uses a three-fold clasp with a secure lock and push-button release. A Hardlex crystal, unidirectional rotating stainless steel bezel and 100m water-resistance rating complete a practical everyday specification.
Research note: this BestBuysUK assessment is based on the manufacturer's published specifications and other reputable technical sources. Specifications and retailer availability can change, so verify critical details before purchase.
