Let’s start with the Seiko ‘Turtle’s case. It’s has got a nicely polished cushion case, nicknamed “Turtle” a derived due to the design of the cushion case. This gives the watch its distinctive look. The SRP 775 features a 120 click unidirectional rotating bezel with a luminescent dot at 12 o clock with black and gold design.

Now some have complaints about the bezel alignment. I can hand on heart say there wasn’t any problem of such from my inspection of the ‘Turtle’. The bezel turns smoothly, hitting the detents crisply and all the way around the dial.

I like the polishing of the case flanks, unmissable is the beautiful smooth polishing of the angles. Good attention to detail by Seiko.

The back of the case features a stainless-steel screw case back with the Seiko logo and also inscribed is the air diver 200 meter.

Seiko ‘Turtle’ SRP 775 Prospex Dive Watch – Movement

The Seiko ‘turtle’ SRP 775 Prospex Dive watch is powered by the calibre 4R36 automatic movement which beats at 3Hz (21,6000 kph).  Calibre 4R36 is made in Japan and features a 41-hour power reserve.

During the time of wearing this watch of 10 – 15hours daily, it loses just 2 seconds from accuracy, which is quite good.


The screw down crown is mounted at 4 o’clock making it comfortable to wear without digging into the skin. 7 mm in diameter, with ridged edges and a polished cap with no logo. There are also gaskets sealing the crystal, case back, and crown.


The Dial

Protecting the dial is Seiko’s trademarked Hardlex  crystal. The crystal settles just below the bezel, adding a level of armour, should in case you hit you hit the watch against a surface. Compared to a crystal glass that protrudes above the bezel.

The Prospex SRP 775 features a matte black dial with gilt print and gold plated Lumibrite hour markers. The large hour and minute hands are centrally mounted, and feature gold-plating that complements the gilt dial and bezel. The design of the luminescent sword-shaped hour hand and arrow-shaped minute hand is copied directly from the original 6309.

On the dial at 3 o’clock is a day/date wheel opening, the luminescent level of the hands and markers is quite generous and very intense. One of the things l appreciate and love about the dial is the large markers and hands make the dial incredibly easy to read at a glance, day or night.

The bracelet is a fine brushed stainless steel. Lovely bracelet as expected from Seiko. Having a prestigious feel and look.

Overall verdict

This is a tough looking watch, throughout the time of wearing the SRP 775 for this review, l could tell that this watch could  and would weather all test. The Seiko SPR 775 will stand the test of time as an everyday watch while still maintaining that gorgeous look.

Watches n Lifestyle rate this watch 8 / 10 and would recommend it any day and any time.
