Description

First produced in 1968, the stunning Seiko Marine Master has been re-imagined for today. Modelled on the original Marine Master MM300, the modern Seiko Prospex Pro Marine Master is certain to impress.

Water resistant to 300 m/1000 ft the Marine Master is built for saturation diving. Made for professional divers, it is deliberately uncomplicated. This allows the quality of the movement and the ergonomic case and bracelet to shine through.  With a one piece structure, the heavy-duty brushed stainless steel case is 44.3mm in diameter. The deep blue dial has high-visibility hour markers and hands coated in Lumibrite. A legible minute track is also at the extreme edge. Surrounding the dial, there is a blue ceramic uni-directional turning bezel in dark blue.

Equipped with an automatic 8L35 calibre movement, the Seiko Prospex Pro Marine Master is accurate to +15 to -10 seconds per day with a power reserve of approximately 50 hours. Presented in a box with an additional silicone strap, this is a first-rate professional divers watch. For complete peace of mind, it is covered by a two year manufacturer’s warranty.

    Dealing with Watch Specialists exceeded all my expectations. Suzie’s customer service is beyond compare and the strap was delivered well before the expected delivery date (and considering I live in Australia, that was really impressive). 5 Stars all round!

    I have once again nothing but praise for suzie and the team ..had a one off custom strap made …it is exceptional.
    Suzie has just helped me on another custom strap matching the colour of the watch hands to the stitching on the strap…this is real service.
