Our vintage offering of the day is an unpolished 5513 Maxi Mk. IV Sub. timestamp: https://imgur.com/a/a73GDTl While modern variations of Rolex watches today are more often equipped on trading floors than sea, prototypes to those marquees were developed for those with utility needs. Yes, the 1680/8's intention and mold were supplied by ocean currents, by depths and near-death. Defined by discipline, the 5513 Maxi Mk. IV Submariner - the last pure tool variegation of thirty years, endangered and collectable and truly vintage - proved divers a worthy Patroclus. This 5513 remains unpolished, whose casemetal is thick and bevels taper softly into lug ends. The black insert has faded into a soft grey, its matte black dial has no blemishes, and the hand and hour makers’ lume has taken on a lovely pumpkin hue. 14,500USD - pricing includes shipping; Venmo, Paypal, Zelle, and wire all accepted forms of payment.
