The Submerciple oozes this nostalgic feeling of the early days of diving, when divers were solely depending upon mechanical watches. It integrates modern engineering technology i.e. Miyota's 90S5 28800bph reliable movement, a sapphire domed crystal, a matte-finish ceramic bezel with engraved markers and Superluminova's brightest C3 luminous material to create an exemplary contemporary implementation of Rolex's original and very rare Submariner ref. 5513. Considering also the truly amazing value for money, all I have to say is "Thank you Mr Oh for giving us such a great watch!".
