Seiko are celebrating 140 years of watchmaking and the green Prospex models really do offer a bold statement on the wrist for those who admire this Japanese brand. Built to high standards, Seiko’s Prospex is a genuine rival to Swiss watches, in all but brand snobbery. You won’t get the same resale value, but you will get a watch that will last a lifetime. Here’s the word from Seiko;

These two mechanical watches in this Iriomote-inspired series are based on Seiko’s celebrated 1968 diver. One is a 300 meter water resistant, eight beat diver’s watch with a unique onepiece case structure. Suitable for saturation as well as air diving, it is made, assembled and adjusted by the skilled craftsmen and women of Shizukuishi and powered by Caliber 8L35. This was created especially for dive watches. The second mechanical watch is a contemporary reinvention of the 1968 original. It houses a six beat caliber and is 200 metres water resistant.

Both are offered as limited editions, of 3,000 and 6,000 respectively. The third watch in the series is a 200m solar chronograph. It, too, is a limited edition of 4,000. All three are presented on stainless steel bracelets but you can buy an extra silicone strap. All three watches will be available in March at Seiko Boutiques and selected Seiko retailers worldwide.

The Prospex 1968 homage retails at 1400 euros, and the heavy duty SLA347 is priced at 3,300 euros. But you get 300m depth resistance and the chunky 44mm case for the extra cash.

Verdict: The `68 homage is the limited edition to go for, great value compared to its big brother. If you have £3000 to invest buy a Tudor Black Bay instead, it will hold its value far better in our humble opinion.
