What is an unpolished case?

Unpolished means nobody has taken a buffing wheel to the case since it was made. It does not mean scratch-free; the opposite, usually. A fifty-year-old unpolished case carries its wear honestly, with fine scratches on the brushed surfaces and small marks on the polished ones, but every edge and every surface is where Rolex put it. A polished case has had those scratches removed by grinding away a layer of steel, which also grinds away the crisp edges, softens the bevels and thins the lugs.

Rolex service centers polished cases as a matter of routine for decades, so unpolished vintage cases are the minority. That scarcity is the whole reason the term matters.

Because polishing is irreversible and cumulative. Every trip to the wheel takes a little more, and after two or three services a case can lose its lug bevels entirely and end up rounded and undersized. A watch with an original dial, original hands and a heavily polished case is a compromised watch; the case is the part you see from across the room. Collectors pay a premium for cases that still have the factory geometry, and on scarce sport references the difference between a sharp unpolished case and a soft one can be the largest single factor in the price after the dial.

Start with the lugs. On an Oyster case each lug has a narrow polished bevel running along its outer top edge, meeting the brushed top surface at a sharp line. If that line is crisp and the bevel is a consistent width along its length, the case is likely untouched. If the bevel is wide, wavy, fading toward the tip of the lug, or gone, it has been polished. Then look at the case side in profile: it should be flat with a sharp corner where it meets the caseback, not bulging. Check the lug holes, which should be round with clean edges, and the crown guards on sport models, which should be symmetrical.

• Crisp, even bevels along the lugs: unpolished.
• Soft, wavy or missing bevels: polished.
• Lug holes stretched into ovals or with rounded edges: polished.
• Brushing that runs the wrong direction or looks freshly applied: refinished.
• Reference and serial engravings between the lugs that are shallow or faint: metal has been removed.

Not really. There are specialists who can recut bevels and re-brush surfaces to bring back the appearance of a factory case, and done well the result can be handsome. But it is still a refinished case with less metal than it started with, and it should be described as such. We do not have cases refinished before sale, and we describe the state of every case honestly. A good vintage watch on a lightly worn unpolished case is the goal; a restored case is a distant second, and a heavily polished one is priced accordingly.

Yes, against the same watch with a polished case, and the premium grows with the desirability of the reference. What it is worth in absolute terms depends on the watch. On a Datejust the difference is real but moderate; on an Explorer 1016 or a Submariner 1680 it can be substantial, because so few survive with sharp cases. The premium also assumes the rest of the watch is right. An unpolished case with a service dial is not a collector's watch, it is a nice case.
