Product Description

The Seiko Prospex Automatic Diver's Watch, SRP639K, with a new caliber 4R36, 24-jewel automatic (self-winding) movement with hand winding capability. It's water resistant to 200 metres. The case is 46.4 mm in diameter and it comes with a black urethane dive strap. Includes a day and date display, super-luminous markers and hands treated with Lumibrite, a black dial, screw down crown, uni-directional bezel, scratch resistant hardlex crystal, and a stainless steel back.

Squeezed within the bezel is Seiko's proprietary Hardlex crystal which is scratch resistant and much more resistant to shattering — which could potentially save the watch if you were diving and had a bad knock against the crystal.

The Seiko Prospex SRP639K has an awesome, straightforward, classic dial design with day and date display. It's a copy of the past, but with modern quality. The indexes are precisely crafted and affixed, the hands also have a great aspect and the overall dial inspires.

The large arrow minute hand is now painted in yellow, again a specific feature of this Seiko Prospex SRP639K.

If you want to read the watch in the dark of night or depths of the ocean, the hour and minute hands are wide and flat and coated with a generous amount of Seiko's legendary Lumibrite lume. The Lumibrite is also not in short supply on the large and deep circle and candle shaped raised indices dotted around the dial and when charged it glows like radioactive waste all night long.

The Seiko Prospex SRP639K features an accordion-style urethane strap which combines high durability and comfort. The accordion-style strap was invented by Seiko in 1975 as a solution to the problem of the expansion and contraction of a diver's wrist at different depths.

The case is precisely crafted and adjusted, the unidirectional bezel feels solid and durable, and the details of the dial and the hands are superb.

Inside the Seiko Prospex SRP639K ticks like a workhorse, but using one of the new generation of Seiko movements. This wrist watch has the new iteration calibre 4R36 ticking inside. It is a self-winding calibre with manual-winding capacity and hacking-seconds features, beating at 21,600 vph, having 24 jewels and a power reserve of approximately 40 hours. This Seiko movement is both extremely reliable and precise.

The Seiko Prospex SRP639K is cool because it's a Prospex. In the Seiko world of watches Prospex simply means 'Professional Specifications'. It's Seiko's answer to the professional world that desires nothing but the very best from their watches.This diver's watch has the famous 'X' Prospex logo printed on its dial. Seiko Prospex watches are sturdy, rugged, reliable and designed for being used in professional conditions.

The Seiko Prospex SRP639K has a comfortable 200 metre water resistance, the required legibility of a proper dive watch — large hands and indexes, highly legible in day-time (good contrast) and in night-time (good lume), with no possible confusion between the indexes (the index at 12 is highly different) and highly differentiated hands (no confusion between the minute and the hour hands possible) — a unidirectional bezel, with a black 60-minute scale and 15-minute area highlighted in yellow.

Many watches bear the label diver's watch but only a small number of these timepieces can be considered fully functional in professional environments. Seiko helped to establish the standard for diver's watches in the International Organisation for Standardisation (ISO). This watch fulfills the ISO 6425 standards for dive watches. If you are an avid diver, this watch is your perfect companion. This Seiko Prospex SRP639K reunites the best of affordable Seiko dive watches with the quality of the Seiko Prospex collection.

A great thing about any Seiko watch is that you can make claim to having a fully in-house made movement and watch. Seiko produce everything themselves which is a feat not many other manufactures can boast.

The Seiko Prospex SRP639K is a bargain. When you look at what this diver's watch really is, you have to realise this is a great deal. The concept of a dive watch, with water resistance over 200m, with a modern accurate movement, with professional specifications, from a manufacture with such a great pedigree. Not just a diver's watch, this is a perfect summer watch for everyone, avid collectors, new comers, rich or not.

Seiko Prospex Automatic Diver's Watch SRP639K Features

  • 46.4 mm wide case
  • Water resistance: 200m Diver
    The watch is designed and manufactured to withstand up to 200 metres going under the water, and is suitable for wearing while scuba diving.
  • Screw-down crown at the 4 o'clock position< br/> The crown has screw-down protection to prevent it from being pulled out by any accidental operation.
  • High legibility
    The dial design has just one objective; maximum legibility, even deep in the ocean where sunlight does not penetrate. The hour markers are large, so as to allow the maximum surface area and depth for Seiko's Lumibrite coating. The hands, too, are wide and easy to read.
  • Unidirectional rotating bezel
    The precise and secure operation of the uni-directional bezel prevent accidental rotation, so that the time measured is never shorter than the actual elapsed time.
