Center chronograph

20 ATM water resistant diver's watch
Ceramic bezel
Small seconds
The HYAKUICHI 11 model is a diver's chronograph watch with a 20 ATM water-resistant case and a chronograph function. The chronograph uses a central chronograph where the chronograph seconds hand is normally stationary, and the small seconds subdial on the left is responsible for keeping time. To achieve the 20 ATM water resistance, both the chronograph buttons and the crown are screw-down locking mechanisms. The tachymeter bezel, which allows for instantaneous measurement of speed by the position of the hand pointing to the engraved slide rule, is made of ceramic, and the contrast with the brushed stainless steel of the case and bracelet is beautifully finished. In addition, it has a 24-hour counter for AM/PM confirmation, a 60-minute counter for measuring time, a date display, a screw-down case back, and a simple, retro locking buckle. It is a sophisticated timepiece that combines high-level performance and design, without any unnecessary embellishments. With its high-spec features and affordable price, its cost-performance ratio is clearly excellent. Suitable for casual wear, and also for books.
This diver's chronograph is perfect for a wide range of situations, from serious marine sports and diving to situations where timekeeping is essential. ■Specifications Quartz (Japanese movement) Chronograph (center chronograph) 24-hour counter (right) 60-minute counter (bottom) Small seconds (left) Ceramic bezel 20 ATM water resistance Date Applied index Screw-down crown Locking buckle Screw-back ■Size Case: H48 x W44 x D13mm (including crown) Bezel diameter: 40mm Dial diameter: 30mm Maximum wrist circumference: Approx. 220mm Weight: 148g (maximum weight) ■Included items Watch Instruction manual/warranty Storage box
