Seiko Prospex Alpinist Automatic Green Dial Brown Leather Strap Men’s Watch SPB210J1


This Seiko Prospex Alpinist SPB210J1 is from the Alpinist collection, first launched in 1959 exclusively for the Japanese market. Hugely popular with many fans worldwide, these new designs are now available globally with an upgraded specification from their original inspiration – a longer power reserve of 70h, and a glass upgrade to Sapphire glass.

Seiko Prospex watches are designed for sports lovers and adventure seekers in the water, in the sky or on land.

This watch is from the Land category and features a bracelet and a stunning green dial similar to the original piece.

Since launching Japan’s first diver’s watch in 1965, Seiko’s innovative watchmaking has changed global dive watch standards.

The Case:

The case of this Seiko Prospex Alpinist SPB210J1 is made from golden stainless steel and is a handsome, utilitarian offering that consists of well-proportioned dimensions, measuring 39.5mm in diameter and 13.2mm in depth. The case features a brushed finish which bolsters the functionality of this timepiece. It also features sapphire crystal glass with an anti-reflective inner coating on the inner surface, as well as a magnifier, which allow for optimum levels of readability. A solid screw-down crown and screw in display case back ensure for superlative levels of dependability and performance.   

The Dial:

The dial comes presented in a sunbeam forest green hue, consisting of a combination of golden Arabic numerals and arrow hour markers. The three o’clock marker has been replaced by a date-window display that is magnified 2.5x by a cyclops. The centre of the dial is occupied by a cathedral style handset, providing the watch with a traditional utilitarian feel. They partly consist of a luminous material which allows for readability in areas of low light. A rotating compass inner ring is present at the outermost edge of the dial, allowing you determine an approximate direction. The Seiko logo is present in gold beneath the 12 o’clock marker.

The Strap:

Crafted from brown calfskin leather and featuring contrasting stitching, the strap of this timepiece pays homage to the motifs of its 1959 original predecessor, providing the watch with an authentic feel. A three-fold deployment clasp with push button release securely fastens the strap around your wrist.

The Features:

Housed inside of the stainless steel case is Seiko’s 6R35 calibre movement which offers an astounding 70 hour power reserve and an accuracy of +25 to -15 seconds per day. The movement type is automatic with manual wind. The movement consists of 24 jewels and offers a hacking function that allows the wearer to accurately set the time.

Free Strap Adjustment

It's important that your watch fits your wrist comfortably and looks great at the same time.

Leather strap watches tend to fit without a problem for most wearers. However, watches fitted with metal bracelets often need adjusting to get the perfect fit.

This is generally a very simple procedure. We can do this for you, or you can get the watch adjusted locally.

Option 1. Specify your wrist measurement and we will adjust it before being sent

When purchasing a watch which has a metal bracelet with adjustable links, we will gladly adjust the watch bracelet to fit your wrist before sending the watch to you - free of charge!

Simply type your wrist measurement (in inches or centimetres) into the bracelet size section of the checkout and we will ensure the watch bracelet is adjusted accordingly before being sent to you. We will include all the surplus links, with the watch.

How to measure your wrist

You can measure your wrist with a piece of string which you can measure against a ruler:

You should allow about half a centimetre (1/4 inch) of slack to prevent it being too tight on your wrist.

In the event of you needing an extra-long wrist bracelet, which requires an extension to the original watch, we must obtain extra links from the manufacturer, and in this event, we will contact you to inform you of any possible delays or applicable charges.

Watches with bracelets adjusted by WatchNation are still eligible under our refund policy.

Option 2. Buy the watch online from WatchNation and have it adjusted locally

If you wish, you can have it adjusted locally by another jeweller or key cutter. However, you will have to cover the cost of this option yourself.
