Prospex Alpinist GMT SPB377

Prospex Alpinist Mechanical GMT. Designed for those who treat life as the ultimate adventure, the Seiko Prospex line meets every challenge with technological excellence and style. Part of a rich legacy of innovation in high-intensity timekeeping, Prospex continues to celebrate a long history of sports watch excellence with recreations and reinterpretations of landmark achievements. Inspired by Seiko’s first sports watch, the 1959 Alpinist, this rugged, yet stylish, watch features the iconic wedge-shaped markers, bold numerals and stylized hands of the original, along with 24-hour GMT timing. An upgraded curved sapphire crystal with anti-reflective inner coating adds reliable visibility, while the new inner rotating compass bezel makes it ideal for hiking and outdoor activities. Framed by a 24-hour GMT bezel, the brilliant blue sunray dial includes a date calendar, LumiBrite hands and markers, and a red-tipped GMT hand. The 24-jewel automatic movement, visible through the see-through screwdown caseback, beats at a frequency of 21,600 vibrations per hour and offers an exceptional power reserve of 72 hours, as well as manual winding capability. Crafted of stainless steel with durable super-hard coating and a secure screwdown crown, this superb timepiece also features a blue calf leather strap with tri-fold push button release clasp. 20 bar, 200M Water Resistant

    DeJaun Jewelers is a step above all the others. Their customer service is top notch . My husband bought my wedding ring there 27 years ago, and it’s still where we go for any of our jewelry needs.

    Excellent service by Nicole. Me and my boyfriend were shopping for an engagement ring, and Nicole took the time to explain to us the different types of diamonds and settings and helped us choose my engagement ring. Nicole is experienced and knowledgable, I highly recommend Nicole when you are looking to shop at Dejeaun Jewelers. Thank you once again Nicole, Rose
