At the heart of this watch lies a Japanese automatic movement by Miyota, model 8215 - a gold standard of precision and reliability that Japan is renowned for. With an oscillation frequency of 21,600 vph (3 Hz), this caliber delivers smooth, consistent timekeeping and a power reserve of up to 40 hours. Housed within a transparent caseback, the hypnotic dance of the rotor is on full display - a visual symphony for the discerning eye.
This stunning timepiece is fitted with a 316L stainless steel bracelet that's as robust as it is elegant. The combination of brushed and polished finishing adds a subtly luxurious visual dimension to the whole. Its metallic grey tone creates a captivating play of light through the natural reflection of polished steel, achieving a seamless transition between sporty attitude and refined elegance. With a 20 mm lug width, the bracelet fits the watch perfectly, emphasizing its modular design and fully integrated silhouette. The deployant clasp makes fastening effortless while providing enhanced wrist security for all-day, all-activity comfort.
The water resistance of this watch is tested to 10 ATM, confirming its ability to withstand pressure down to 100 meters underwater - making it the perfect companion for swimming and recreational diving. Built to handle the most demanding wet environments without compromising performance, its solid construction featuring a screw-down caseback ensures no water can reach the internal mechanism. The reinforced crown seal minimizes infiltration risk, delivering unwavering reliability even in the wettest conditions. This level of water resistance makes it not just a style statement, but the go-to choice for those who live an active, adventure-filled life.
