There was no Oyster Perpetual 41 QC thread yet. Facts from Rolex: reference 124300 was introduced in 2020, with a 41 mm Oystersteel case, a domed bezel and water resistance to 100 m. It uses calibre 3230, with about 70 hours of power reserve and a precision of −2/+2 seconds a day once cased, according to Rolex’s Superlative Chronometer certification. In 2025 Rolex introduced reference 134300, with a redesigned case and a slimmer Oysterclasp.
Which calibre each reference uses is explained in Rolex calibres 3230, 3235, 3285, 3255 and 4131, and how to read reference numbers in how to read a Rolex reference.

Editorial summary, not independently verified.
The dial first. It’s a watch with no date and no Cyclops, so everything shows:
- The applied crown logo, centred and with clean edges.
- The applied indexes straight and at the same distance from the edge, with the Chromalight luminescent material evenly filled.
- The text sharp, with no blurred edges and no letters thicker than others.
- Rolex offers dials with a sunray finish and lacquered colour dials. Judge the colour in daylight, never with flash alone.
Newbie question: with no date and no Cyclops, what’s left to check? It seems like the brand’s simplest model.
That’s exactly why the finishing matters more. The domed bezel is polished: in photos the reflection should run as a smooth, continuous line all the way round, with no flat zones or jumps. The case combines brushed and polished surfaces, so look for sharp transitions between the two, not a blurry band. The finishing guide is in brushed or polished in QC photos.
The crown: the screw-down Twinlock, with the crown logo centred, screwed down flush with the case.

The bracelet. Rolex describes the Oyster on this model with solid links, an Oysterclasp and the Easylink comfort extension of about 5 mm. In photos:
- The links aligned, with no gaps that differ from one side to the other.
- The clasp closed flush, not lifting at one end.
- A photo with the Easylink open, to see that the link unfolds straight.

Profile and caseback. Ask for a photo exactly at 9 o’clock: the case, the bezel and the bracelet should read as one continuous line, with no visibly taller middle case. The screw-down caseback: sharp engravings and a clean fit.
Rolex lists a hacking seconds function, so with the crown in the time-setting position the seconds hand should stop. That’s a short video you can ask for.
So: daylight for the dial, the bezel reflection, the bracelet with the Easylink open, the 9 o’clock shot and the hacking video. And the 100 m water resistance?
Summary:
- Dial: applied crown centred, indexes straight and evenly filled, sharp text; colour in daylight.
- Domed bezel: one smooth, continuous reflection, no flat zones.
- Case and crown: sharp transitions between brushed and polished; Twinlock centred and flush.
- Bracelet: links aligned, clasp flush, Easylink open in a photo.
- Profile and seconds hand: a 9 o’clock shot and a video of the seconds hand stopping.
Not checkable on photos: water resistance, precision and the movement itself.

Thanks. The bezel reflection and the 9 o’clock shot are the first things I’d ask for.
