Here is a nice like new example of the Seiko 50th anniversary Tuna SRP-655.

Sometimes referred to as the “Baby Tuna”, it is a great watch – big but wears smaller due to slightly concave back.  It features a comfortable rubber bracelet, and lume is outstanding.  At 20% or less of the price of the Darth Tuna and its other big brother Marine Master watches, this is a steal and lot of bang for your buck.

High legibility

The dial design has just one objective; maximum legibility, even deep in the ocean where sunlight does not penetrate. The hour markers are large, so as to allow the maximum surface area and depth for Seiko’s Lumibrite coating. The hands, too, are wide and easy to read.

Unique design of the bezel enhance the operability

The deep grooves in the bezel are designed for easy operation, even when diving gloves are worn.


Water resistance : 200m Diver
The watch is designed and manufactured to withstand up to 200m going under the water, and is suitable for wearing while scuba diving.

Screw-down crown

The crown has screw-down protection to prevent it from being pulled out by any accidental operation as the water resistance function is secured only when the crown is at its normal position.


The Seiko 50th Anniversary Tuna SRP-655 is complete with box and papers.  Warranty card is not filled in.

A great watch at an attractive price.
