Prospex Alpinist SPB121J1 Watch

The Watch
Legendary watchmaker Seiko unveils its Collector timepiece from the Prospex Alpinist collection - a triumphant return for a model that earned its place in horological history decades ago. Now reimagined for a new generation, this iconic piece brings its timeless elegance and refined character to the modern wrist. Designed for men, it pairs natural sophistication with true versatility, transitioning seamlessly from everyday wear to underwater adventures. The robust stainless steel case measures 39mm in diameter. At 3 and 4 o'clock, two crown pushers allow you to adjust the time and operate the built-in compass. A sapphire crystal sits above the dial, providing exceptional scratch and impact resistance. A fixed stainless steel bezel adds an extra layer of durability. The screw-down caseback ensures the watch is fully equipped for diving.

The Dial
This Seiko watch features a beautiful round dial in a rich green hue. A sunray finish catches the light every time you glance at the time. Around the dial's edge, compass direction markers add a functional, adventurous touch - positioned just inside a finely detailed minute track for added precision. Arabic numeral and triangular indexes in gold tone are arranged across the dial. At the center, two hands and a seconds hand - all gold tone and treated with SuperLuminova - deliver accurate hours, minutes, and seconds throughout your day. At 3 o'clock, a white date window keeps you on schedule. Just above the 6 o'clock index, the water resistance rating and movement type are engraved on the dial. Below the 12 o'clock index, Seiko's name is displayed in its signature gold tone.

The Movement
This timepiece is powered by an automatic movement, delivering long-term reliability and driving the Alpinist with precision. Developed in-house by Seiko, the caliber 6R35 ensures accurate timekeeping day in, day out - with an impressive 70-hour power reserve.

The Strap
This timepiece is fitted with a gorgeous brown leather strap that brings a vintage character to any men's wrist - a detail worth showing off. Perfectly matched to the overall aesthetic of the watch, it maintains that refined look with tone-on-tone stitching for a polished finish. A pin buckle closure keeps everything secure.

Water Resistance
With a water resistance rating of 200 meters - or 20 ATM, for those who appreciate the finer points of watchmaking terminology - this timepiece is built for recreational diving. It handles showers, baths, ocean swims, and shallow-water diving with ease. That said, for professional scuba diving with tanks, our Ocarat watch specialists have hand-picked a selection of 30 ATM models available in our catalog - just run a quick search on our site. One last word of advice: never press the pushers or manipulate the crown while the watch is in the water.
