Rolex 3348 Oyster Perpetual Bubbleback "Lifesaver"

Oyster Perpetual -> 3348

The 3348 is a stainless steel Oyster Perpetual Bubbleback, 29mm, that Sotheby's catalogued under the nickname "Lifesaver Bubbleback" when it came up for sale in New York in 2018. The name is Sotheby's own, not an official Rolex term or one otherwise documented in wider collector use — worth noting rather than repeating uncritically. What is well documented is the retail history: the dial carries a second signature for Mappin & Webb, the British jeweller and silversmith, placing this example through one of Rolex's established period retail partners.

Where it sits in the line

The 3348 is a plainer, all-steel counterpart to the pink-gold-and-steel bi-metal Bubblebacks like the 3064 and 3130 — no bezel or lug decoration in precious metal, a flat rather than domed or engine-turned bezel, and a more modest 29mm case. It represents the lower cost tier Rolex sold alongside its gold and bi-metal Bubblebacks through the same period.

Production outline

The Sotheby's example is dated circa 1940, case no. 154006, retailed through Mappin & Webb. It went to auction at Sotheby's New York on 24 May 2018 (sale N09879, lot 136) against a $5,000–7,000 estimate and did not sell — a genuine market data point worth recording alongside the successful results documented for other Bubbleback references, not every catalogued example finds a buyer at its estimate.

A second documented 3348 shows Rolex offering the reference in a different metal tier entirely: 14k pink gold and stainless steel bi-metal, 29mm round case, on a matching pink gold and steel bracelet with deployant buckle. Its cream Arabic-numeral dial carries a Serpico y Laino retailer signature — the Caracas-based dealer whose signed dials appear across several other Rolex references of the period, including the 3130.

Movement notes

Sotheby's lot description confirms an automatic movement; no caliber number or jewel count is specified in the catalogue text.

Dial map

The Sotheby's example carries a silvered dial with painted Arabic numerals and dot hour markers, a subsidiary seconds sub-dial, and an outer minute-division track, with dual signatures for Rolex as maker and Mappin & Webb as retailer. The second documented example carries a cream dial with painted Arabic numerals, a subsidiary seconds sub-dial with a printed 30/60 minute track, blued steel hands, and a Serpico y Laino retailer signature beneath the Rolex Oyster Perpetual signature.

Case, bezel, crystal, and crown

29mm stainless steel case with a flat bezel — plainer than the domed or engine-turned bezels documented on other Bubbleback references — screw-down case back and crown. Sotheby's lists an associated (non-original) expansion bracelet sold with the watch.
