Rolex Bubble back , "anse cashe rigate" pink gold california dial

This Rolex Oyster Perpetual Chronometre Bubbleback Ref. 3595 is a remarkable example of early Rolex design in stainless steel and pink gold. Its warm pink California dial combines Roman numerals at 10, 11, 1, and 2 with Arabic numerals at 4, 5, 7, and 8. A triangle at 12 and geometric markers at 3, 6, and 9 complete the distinctive high-visibility layout. Blue-steel luminous hands, a railway minute track, and the pink-gold bezel provide a finely balanced contrast against the aged dial. Yet it is the architecture of the case that gives this particular reference its defining identity.

Collector's Note

The Ref. 3595 belongs to the family of hooded Bubblebacks made during the 1940s. The Bubbleback name refers to the deep, domed caseback that accommodated the early Rolex automatic movement. On the Ref. 3595, the steel case is paired with pink-gold elements, creating a highly characteristic two-tone execution of the period. The California dial was developed by Rolex as a clear and instantly legible format for a compact wristwatch. Its mixture of Roman, Arabic, and geometric hour markers has since become one of the most recognisable designs in vintage Rolex collecting.

The key rarity of this reference lies in its covered lugs. Hooded-lug Bubblebacks are already an uncommon and distinctive construction, with the gold hoods extending over the ends of the bracelet to create a more integrated case profile. The Ref. 3595 goes further with horizontal ribbing cut into these hoods. This ribbed treatment adds depth, catches the light across the pink gold, and is appreciably less frequently encountered than plain covered lugs. It turns the lugs from a structural detail into the central design feature of the watch. Together with the pink California dial and matching two-tone expandable bracelet, the ribbed hooded-lug architecture makes this Ref. 3595 an unusually expressive version of the classic Bubbleback.
