This Seiko watch from their Prospex collection ensures flawless operation thanks to the mechanical-automatic movement with manual winding and 24 rubies in its mechanism. It has a power reserve of approximately 70 hours and a second-hand stop function when adjusting the time, along with a calendar function that displays the date in a small window located at 3 o'clock on the dial. The watch, both the 38mm diameter case and the bracelet with a triple-fold clasp with a push-button release, is made of stainless steel, an enduring material. The blue dial is covered by a curved sapphire crystal with anti-reflective coating on its inner surface. LumiBrite material present on the hands and indices ensures readability in low-light conditions. Lastly, it is worth noting that this watch is water-resistant for daily use, up to 20 bars.
