The Sea-Dweller was born after the collaboration between Rolex and the French underwater engineering company Comex in 1967. Initially the Comex divers were using the Submariner, but found there was a risk of the crystal shattering due to the pressure from the build up of helium in the watch. This led to the design of a small valve opposite the crown. When the watch reaches a certain depth beneath the water, the pressure triggers a piston which pushes against a gasket and sealing the watch. When resurfacing the pressure from the helium inside the watch opens the valve and allows the gas to escape.
Over the years this iconic tool watch has evolved and been produced with slight differences in dials. These are highly sought after by collectors and are known by various nicknames among the collector community. The Rail Dial earns its nickname from the Cs in chronometer and certified lining up like railway tracks. The Rail Dial was only produced for two short years between 1977 and 1979.

Damage, Restoration, Alteration & Functioning

Although every effort is made to note any damage, restoration or alterations, the absence of any such information in catalogue descriptions does not imply the lot is in perfect condition and free from any such defects. Prospective buyers should satisfy themselves as to the condition of any lot prior to bidding. Dreweatts condition reports will identify whether a watch functions, and any restorative work that needs to be carried out for the watch to function properly. Dreweatts are unable to test watches for accuracy or running to time, and we do not guarantee that any watch will function when purchased. Dreweatts recommend that any watch purchased from us is subsequently overhauled by a competent watchmaker to ensure proper functioning.

Dreweatts watch specialists are available to answer any queries, and will be on hand during the view for further advice

All watch movements have been inspected by Dreweatts watchmaker and specialists, and we have verified all inventory and movement numbers. For the information of potential bidders, all inventory and movement numbers are printed in the catalogue description for the relevant lot

Artist's Resale Rights (“Droit de Suite”)

Lots marked with a delta symbol (δ) are subject to the Artist's Resale Right Law.The buyer agrees to pay Bloomsbury Auctions an amount equal to the resale royalty and we will pay such amount to the artist's collecting agent. Resale royalty applies where the Hammer price is 1,000 Euros or more and the amount cannot be more than 12,500 Euros per lot. The amount is calculated as follows:

Royalty For the portion of the Hammer Price (in Euros)
4.00% up to 50,000
3.00% between 50,000.01 and 200,000
1.00% between 200,000.01 and 350,000
0.50% between 350,000.01 and 500,000
0.25% in excess of 500,000

Invoices will, as usual, be issued in Pounds Sterling. For the purposes of calculating the resale royalty the Pounds Sterling/ Euro rate of exchange will be the European Central Bank reference rate on the day of the sale.
