Sea-Dweller 43

The Sea-Dweller was developed for professional saturation divers, and reference 126600 carries that brief in a 43mm Oystersteel case rated to 1,220 metres, with a helium escape valve on the case side.

A single line of red text — “Sea-Dweller” — recalls the first models of 1967, set on a black dial beneath a black Cerachrom diving bezel. For the first time in the line, a Cyclops lens magnifies the date.

Every piece is examined in Johannesburg before final delivery: reference, serial and movement checked against the description, condition photographed, and documents compared with the watch.

Original manufacturer packaging is preserved and travels inside a neutral protective outer box. Have water resistance tested at each service; avoid magnetic fields and impact, and keep the watch wound or on a winder if worn infrequently.

Delivery. Within South Africa only. Checkout shows one Shipping & Secure Delivery charge, plus customs duty and the 15% import VAT for this exact piece — both collected upfront so nothing is payable on delivery. Shipping is never free. High-value pieces may require manual approval and specialist insured transport.

Returns. Your statutory rights under South African consumer law are not affected. Damaged, defective or materially misdescribed pieces are handled as the law requires; change-of-mind returns must be unworn with all tags, box and documents. Read the draft returns policy (attorney review pending).

Warranty. Where a dated manufacturer warranty card is supplied, the warranty is the manufacturer's and is subject to its terms. Maison Monde does not itself offer a manufacturer warranty.

Rolex developed the Sea-Dweller in 1967 with professional divers, adding the helium escape valve it later patented. It sits alongside the Submariner as the brand's deep-diving instrument.
