Seiko Prospex SNR029

The Seiko Prospex SNR029 is part of the high-end Prospex LX line, combining serious diving capability with advanced Spring Drive technology. Its 44.8mm titanium case has a super-hard coating, giving the watch a strong yet refined feel. The design also features a sapphire crystal with an anti-reflective coating on the inner surface.

At the heart of the watch is Seiko’s 5R65 Spring Drive movement. It offers approximately 72 hours of power reserve, along with a power reserve indicator and date display. Accuracy is rated at ±15 seconds per month, or around ±1 second per day.

Built for demanding underwater use, the SNR029 provides 300-meter water resistance for saturation diving. A unidirectional rotating bezel, screw-down crown, and screw case back further support its professional dive-watch design.
