A sporty 40mm chronograph pairing a deep black dial with a polished silver finish.
The black dial creates a sharp, high-contrast appearance, while the chronograph layout adds a technical, performance-inspired edge. Its rounded octagonal case delivers the distinctive Nautilus-style profile with a clean, versatile presence.
Powered by a Seiko VK63 quartz chronograph movement, the watch is built from 316L stainless steel and protected by mineral glass. A screw-down crown and 5 ATM water resistance add practical protection for everyday wear.
