Seiko Essentials SRPH87

Essentials Collection
From the Essentials Collection. Adding classic automatic timekeeping to the Essentials Collection, this versatile timepiece winds with the movement of the wearer’s wrist, and never needs a battery. Visible through the screwdown see-through caseback, the 23-jewel movement beats at a frequency of 21,600 vibrations per hour, with a power reserve of approximately 41 hours and manual winding capability. With a sophisticated sunray finish, the blue dial includes a calendar and crisply defined hands and markers. Crafted of stainless steel, with tri-fold push button release clasp. 10 bar, 100M Water Resistant.
