What the differences cost you
Each note below follows from the published figures in the tables above — what they mean for intake, for a listing, and for the handover. Nothing here estimates a price or a margin.
Different movements to verify and to service
The 126334 runs the Calibre 3235, Manufacture Rolex and the 134303 the Calibre 3230, Manufacture Rolex. Two consequences at intake: the service history that is normal for one calibre is not evidence about the other, and the calibre is the check that catches a movement swapped into the wrong case. Confirm the movement matches the reference rather than assuming it from the dial.
What to check on each
126334
- Treat the fluted bezel as gold, because it is. White gold takes marks more readily than steel and the flute peaks are exactly where a careless polish rounds the profile.
- Check the flute edges are even all the way round. A bezel that has been polished shows flattened peaks on the side that sat against a desk, and the asymmetry is visible once you look for it.
- Note the clasp is an Oysterclasp rather than the Oysterlock used on the sports references — there is no safety catch, which is correct here and not a missing part.
134303
- Check the clasp is an Oysterclasp rather than an Oysterlock. Rolex specifies the plain folding clasp here with no safety catch, and its absence is correct rather than a missing part.
- Note that the bracelet is Oystersteel while the case is Yellow Rolesor. The gold is in the case and bezel, not the band, and a buyer expecting gold links will be disappointed.
- Confirm there is no date aperture and no Cyclops on the crystal, both of which are correct for this reference.
