The stunning Seiko SKX007 'Moonlight Shadow' GMT, Seiko Mod Watch.
Taking Seiko's discontinued SKX007 to the next level and modding it into the quality that it should be, a no-expense spared mod!

Youtube video of the watch here -

Base watch is an SKX007 case with drilled lugs for easy strap changes, it is fitted with a coin edge stainless steel bezel ring from Crystal Times and the stunning blue black GMT bezel insert is sapphire crystal, will never scratch! it also has a subtle green lume added.
The crystal is a double-domed sapphire crystal with blue anti-reflective coating on the underside, and a bevelled edge to keep the seiko DNA, I wasn't going for a sub style look here, I wanted it to be a true seiko style piece, just the best it could possibly be, this is a huge upgrade on the Seiko Hardlex, this sapphire will not scratch. 
As the watch is based on the SKX007, I add a signed screw down crown, which gives it a 200m water resistance, a massive upgrade to the Seiko SSK GMT range, which is only 100m, due to the lack of the screw-down crown.
The caseback is a domed stainless steel display back with sapphire crystal from Crystal Times.
Then there is the stunning Siko OEM dial which is a deep blue textured Dial which is from the Seiko PROSPEX Samurai SRPB49K1. This dial has to be modified to fit a Seiko GMT movement but widening the centre hole and removing the feet on the back and adding new feet to to fit the 3.8 o'clock crown position, as the original Samurai watch was a 3 o'clock crown position.
The hands are Silver Samurai with the blue GMT hand.
A black 24 hour GMT chapter ring is added to complement the GMT function of the watch.
The Movement is Seiko's new NH34 GMT, which is Automatic, Hacking with the ability to also be hand wound, so you don't have to shake to wake for 2 minutes and you can set the second hand. It has a power reserve of 41 hours.
The bracelet is a high quality solid link and solid end link Jubilee, a nice upgrade from the standard Seiko jubilee, very sturdy on the wrist, not clanky like the original.

This piece has been massively upgraded and feels amazing, a lot more usable and robust feeling on the wrist. A true classic upgraded to beat the best of diving watches! Why buy a standard Seiko GMT when you can spend a little extra and get a true heirloom piece like this!


The watch has pressure tested to 200m and the movement regulated to be very accurate.

As you can see, modded to the highest spec using the highest quality parts, a completely indulgent piece! An absolutely stunning quality watch!
