The SEIKO SSH153 Astron 'Silvery Night' embodies Seiko's ethos of innovation and durability. Its titanium case, coated for extra hardness, houses a distinctive 'silvery night' dial protected by dual sapphire glass. A black ceramic bezel complements its sleek, angular design, aiming for a comfortable fit with a low center of gravity.

Powered by the advanced 5X83 solar movement, the watch not only charges efficiently but also boasts a precise one twentieth of a second chronograph function. It maintains exceptional accuracy, deviating only ±15 seconds per month (±1 second per day), with a generous power reserve of approximately 6 months when fully charged, extendable to around 2 years in power save mode.

With water resistance up to 100m, it is suitable for daily adventures. The dual-curved sapphire crystal, coated for enhanced clarity, ensures durability in various conditions. Lumibrite on the hands and indexes enhances visibility in low-light environments.

Packed with features, including automatic hand position alignment, day display, DST, and a perpetual calendar, it also offers magnetic resistance up to 4,800 A/m. The clasp includes a Smart Adjuster function for easy adjustment.

Measuring 43.3mm in diameter and 13.4mm in thickness, with a lug width of 14.0mm, it strikes a balance between boldness and wearability. The SEIKO SSH153 Astron combines cutting-edge technology with a stylish design, appealing to enthusiasts who value both innovation and aesthetics.
