Additonal information:
The case is based on the modern SPB143 adaptation of the 62MAS case with super fine brushing and highly polished bevelled highlights along the sides. The case features drilled lugs, screw down crown and case back. 
The AR coated Sapphire crystal has a very sleek low dome formation.
The case is double bevelled which provides un-parallel comfort on wrist. 
The brushed steel bezel insert features large legible markers and also has a flush pip at the 12. The 120 click unidirectional rotation is smooth with the right amount of resistance.  
The dial is based on vintage printing but with a very cool steely blue sunburst effect and paired with micro-detailed hands. The lume is also great with ample glow. 
The bracelet supplied is excellent, with solid end links using 2.5mm spring bars and it features brushed, flattened links with polished bevels on top and bottom of each link. The clasp is a 3 micro adjustment flip lock with milled internals. 
The additional strap is an elasticated army style strap which pairs perfectly with the colour scheme of the watch. 
The movement is a Seiko NH35 automatic movement which has been regulated to perform in or around +/- 10 secs a day and features a hackling and hand winding capability with a quick set date complication. (DO NOT SET THE DATE BETWEEN 10PM - 3AM)
Water resistance has not been tested but for all new components and seals have been used. currently splash proof but recommended to get it professionally tested if it to be used for diving.
