Seiko Prospex – SRPB61K1

This time round I had the opportunity to handle a “not so new” Seiko Prospex model, the SRPB61K1. This is a 2019 model released under the Prospex Sky sub-brand. It is a pilot style watch that is powered by the 4R35 automatic movement and has a bi-directional rotating slide rule bezel for performing mathematical calculation/conversion during flight. It has a diameter of 44.7mm and uses a curved Hardlex crystal.
