Rolex 3064 Oyster Perpetual Bubbleback

A checked version of this page, approved on 16 August 2026, was based on this revision.

The 3064 is a tonneau-shaped Oyster Perpetual Bubbleback from around 1940, built in pink gold and stainless steel with hooded lugs and a pink dial. Its only publicly documented example carries an unusual retail history: sold new through Dobbies Ltd. of Nairobi, a Kenyan retailer, and signed on the dial to prove it. Colonial-era East African retail signatures are rare next to the Swiss and European names that dominate Bubbleback dial signatures, and this one survived on the watch through to a 2014 Christie's sale.

Where it sits in the line

The 3064 belongs to the same tonneau-cased, pink-gold-and-steel bi-metal group as the 3130 and 3133, sharing the 9¾-ligne movement class and hooded-lug case style common to Rolex's early automatic Oyster Perpetuals. What distinguishes its one documented example is provenance rather than construction: a retailer signature from Dobbies Ltd. of Nairobi, placing the watch in Rolex's colonial East African retail network rather than the Swiss or London houses that signed most surviving Bubblebacks.

Production outline

The only documented 3064 is dated circa 1940 by Christie's, case no. 282'453, and sold at the house's Geneva sale on 12 May 2014 (sale 1401, lot 240) for CHF 10,000 against a CHF 8,000–12,000 estimate. Christie's own cataloguing calls it directly a "bubble back type case" watch, removing any ambiguity about family classification.

Movement notes

Caliber 9¾ (ligne class), automatic, 18 jewels, chronometer-certified — the same movement-size class documented on the 3130, 3133, and 3725 references from the same generation.

Dial map

The dial is pink with luminous Arabic and baton numerals and luminous hands, a subsidiary seconds sub-dial, and dual signatures: Rolex's own maker's signature alongside the retailer's mark for Dobbies Ltd., Nairobi. Retailer-signed Bubbleback dials are documented across several references from major houses like Serpico y Laino and Bucherer; a colonial East African retailer signature is a less common variant of the same practice.

Case, bezel, crystal, and crown

32mm tonneau-shaped case in stainless steel, with an 18k pink gold bezel and hooded lugs, screw-down case back and crown, the crown itself in pink gold. The bi-metal construction — steel case body, gold bezel and lugs — is a cost-tier choice documented across several Bubbleback references of this generation rather than unique to the 3064.
