The size
We do not ask you for it. The atelier's archive knows the Oyster Perpetual references one by one: the lug width, the case, the years. Below is what the archive says today; from the reference, the rest follows. The watch remains on your wrist.
What changes for the strap
The strap takes the place of the bracelet and its end links, and the end follows the profile of the case between the two lugs. What size your reference has is told by the archive.
The leather
Alligator, box calf, suede, shell cordovan: the leather is chosen together, in the atelier or by video call. Where it enters between the lugs, the strap is as thin as needed; at the wrist it returns to its thickness. The calf lining, the edges painted in several layers, the hand stitching in saddle stitch.
The time
Four, five weeks from confirmation. In the atelier in Via XX Settembre or by video call, wherever you are. Care for the first eighteen months is included.
The next step
The right strap is not chosen. It is built together.

From the 1002 to today's cases
The Oyster Perpetual brings together two Rolex inventions: the waterproof Oyster case of 1926 and the self-winding Perpetual rotor, patented in 1931. It is the brand's most essential model: hours, minutes and seconds only, on an Oyster bracelet. Among the historic references is the 34 mm 1002; since 2020 there have been five cases, from 28 to 41 mm, with lug widths from 14 to 21 mm.
The 1002
The 1002 is the 34 millimetre Oyster Perpetual of the Sixties, Seventies and Eighties, with the calibre 1570. Lug width, 19 millimetres.
Oyster Perpetual 36
The 36 millimetre case has a 20 millimetre lug width; with the 126000 of 2020 the calibre 3130 gives way to the 3230.
Oyster Perpetual 34
The 34-millimetre case changes size with each generation: 19 millimetres between the lugs on the 114200, 18 on the 124200 from 2020, which carries calibre 2232.
Oyster Perpetual 39
The 114300 is the 39-millimetre Oyster Perpetual, in the catalogue from 2015 to 2020 with calibre 3132. Between the lugs, 20 millimetres.
Oyster Perpetual 41
In 2020 the 124300, 41 millimetres, takes the place of the 39-millimetre case; the 134300 that follows it has lugs with a slimmer design. Between the lugs, 21 millimetres.
The small cases
Oyster Perpetual 31
The 277200, from 2020, has a 31-millimetre case and the calibre 2232. Between the lugs, 16 millimetres.
Oyster Perpetual 28
The 276200 from 2020 is the smallest case in the collection, 28 millimetres, with the calibre 2232. Between the lugs, 14 millimetres.
