Vintage watch terms, explained in plain English
Every word you'll meet in a vintage watch listing, from patina to calibre, in a sentence or two. Where it changes what you should pay or check, we say so.

Most of these come up in the first few listings you read. Some just need a translation. A few, like redial, gold-plated and spotting, are the words that decide whether you're paying a fair price. Where we've written a full guide, the term links to it.
The dial
The face of the watch, and where most of a vintage watch's value lives. It's also where most of the trouble hides.
- Patina
- The even, natural ageing of a dial, hands or case over decades: a cream tone on white paint, a warm glow on the markers. Even patina is generally welcomed, because it suggests nobody has repainted the dial.What is patina? →
- Spotting (foxing)
- Small brown or dark spots across a dial, usually from moisture getting in at some point. That's damage rather than patina, and it takes value off. In the 1,883 dials we looked at, spotting turned up seven times as often as even ageing.Patina vs damage →
- Tropical dial
- A black dial that has faded evenly to brown over the years, usually from sunlight. Collectors pay a premium for a good one, which is why fakes exist. Ask how it got that colour.Tropical dials explained →
- Fauxtina
- Fake patina: lume or paint made to look aged on a new watch. Fine on a modern piece when the brand says so. On a vintage listing it's a warning sign.
- Redial
- A watch whose dial has been repainted, refinished or replaced. The rest of the watch can be completely genuine. About 1 in 100 vintage listings admit one, rising to about 1 in 40 between £1,000 and £2,000, and those are only the sellers who say so.What is a redial? →
- Service dial
- A replacement dial the brand itself fitted during a service. It's genuine, but it isn't original to the watch, so collectors value it below an original dial and above a redial.
- Lume
- The glowing paint on the hands and hour markers. On old watches it often turns cream or brown, and how it has aged is one of the quickest clues to whether a dial and hands are original.
- Tritium
- The lume used on many watches from the 1960s to the late 1990s, often marked with a T on the dial. It no longer glows much, and it usually ages to an even cream. Evenly aged tritium is one of the loveliest things on a vintage dial.
- Radium
- The lume on many watches before the 1960s. It's mildly radioactive. Safe to wear with the case closed; never open it or scrape the dial yourself.
- Pie-pan dial
- A dial with a raised centre and sloping edges, like an upside-down pie dish. Best known on 1950s and 60s Omega Constellations, where it adds noticeably to the price.
- Sector dial
- A dial divided into rings and segments, often with a separate minute track. For our money, one of the best-looking dial designs of the 1930s and 40s.
- Applied markers
- Hour markers made as separate metal pieces and fixed onto the dial, rather than printed. They catch the light, and they're a sign of a better-made dial.
- Relume
- Fresh lume painted over the old on the hands or markers. It's a repair, so it should be described. If the hands glow bright white but the dial markers are cream, ask.
The case and what it's made of
The metal around the movement. What it's made of moves the price more than almost anything except the brand.
- Solid gold
- A case made of gold all the way through, stamped with a carat mark such as 750 or 18K. Careful: 18K followed by letters (GP, RGP, electroplated) means plated, not solid. On the same brand, solid gold vintage watches are listed for between a quarter and two-thirds more than gold-plated ones.Is my watch real gold? →
- Gold-filled
- A thick layer of gold bonded to a base metal. It wears far better than plating and was built to last decades; rolled gold plate is the same idea with a thinner layer. If we had to pick one for daily wear on a budget, gold-filled would be it.Gold-filled vs solid gold →
- Gold-plated
- A very thin layer of gold over steel or brass. It wears through at the edges with use. It can be replated, but a replated watch is worth less than one with its original plating.How to tell →
- Gold-capped
- A thick gold shell over a steel case, used by Omega and a few others. Better than plating, below solid gold. The steel case back is normal.
- Hallmark
- The stamp that says what metal a case is. 750 means 18 carat gold, 585 means 14 carat, 375 means 9 carat, and 925 means sterling silver.Reading the marks →
- Case back
- The back of the case. It's where the reference number, serial number and metal marks usually are, so it's the first photo to ask a seller for.
- Reference number
- The model number the maker gave the watch, often engraved on the case back or between the lugs. Search the reference, not the brand name, and you're comparing like with like.Example: finding a Gucci's reference →
- Serial number
- The number unique to your watch. It can help date it, but it doesn't change what it's worth.
- Bezel
- The ring around the crystal. On some watches it turns (divers use it to time a dive); on others, like Gucci's change-bezel bangle, it swaps out for a different colour.
- Crystal (acrylic, mineral, sapphire)
- The clear cover over the dial. Most older mechanical watches have acrylic (Omega calls theirs hesalite), which scratches easily but polishes out. Many 1980s and 90s quartz watches have mineral glass. Sapphire is the hardest and arrived later.
- Lugs
- The four horns that hold the strap. Sharp, crisp lug edges suggest a case that hasn't been heavily polished.
- Polished case
- A case buffed to remove scratches. A light polish is fine. Heavy polishing rounds off the edges and blurs the marks, and collectors pay less for it.
- Unpolished
- A case that has never been buffed, with its original edges and finish. Collectors pay more for it, so sellers say it often. Look at the lug edges before you believe it.
- Recased
- An original movement and dial moved into a different case, often because the old one was damaged. Should be disclosed, and should be cheaper.
- Signed crown
- A winding crown with the brand's logo on it. A plain crown on a watch that should have a signed one usually means a replacement part.
The movement
The engine inside. You rarely see it in a listing, which is exactly why you should ask for a photo.
- Movement
- The mechanism that keeps time. Ask the seller for a photo of it: a clean movement tells you more about how a watch has been looked after than the dial does.
- Calibre
- The maker's name or number for a movement, such as Omega cal. 561. It decides how easily a watchmaker can get parts, so a common, well-loved calibre is a comfort, not a compromise.
- Automatic
- A mechanical watch that winds itself as you wear it, using a weight that swings with your wrist. Take it off for a day or two and it stops.
- Manual wind (hand-wound)
- A mechanical watch you wind by turning the crown, usually once a day. Most watches before the 1950s work this way, and plenty of people love the daily ritual.
- Quartz
- A battery-powered movement, common from the late 1970s. Very accurate and cheap to run. Most vintage fashion watches, Gucci included, are quartz.
- Bumper automatic
- An early automatic from the 1940s and 50s whose weight bumps against springs instead of spinning all the way round. You can feel it knock gently on the wrist. That's normal.
- Jewels
- Tiny synthetic rubies used as bearings to reduce wear. A good manual watch usually has 17, an automatic 21 to 25. More isn't automatically better.
- Chronograph
- A watch with a stopwatch built in, run from pushers on the side of the case. Not the same as a chronometer.
- Chronometer
- A watch whose movement passed an official accuracy test, and says so on the dial. Not the same as a chronograph, though sellers mix the two up all the time.
- Service
- Taking the movement apart, cleaning it, oiling it and putting it back together. A mechanical watch wants one every five to ten years. Ask when it was last done, and for the receipt.
Buying and condition
The words sellers use in listings, and what they actually mean for you.
- NOS (new old stock)
- A watch made years ago that was never sold or worn. Genuinely rare, so treat the label with healthy suspicion and ask how they know.
- Frankenwatch
- A watch assembled from parts of different watches, sometimes from different brands. Fine if you know and the price reflects it. A problem when it's sold as original.How to spot a fake →
- Full set (box and papers)
- The watch with its original box and paperwork. It adds real value on Rolex and Omega. On fashion brands it matters far less than people expect.What adds value on a Gucci →
- Aftermarket
- Any part that didn't come from the original maker: a strap, a buckle, a crystal. A new strap is normal and harmless. Aftermarket hands or a dial take real value off.
- Service history
- Proof of when and where a watch was serviced. A recent service from a named watchmaker is worth asking for, and worth paying a little more for.
- Water resistance
- Treat every vintage watch as not waterproof, whatever the dial says. Seals perish over decades, and a splash is the most expensive mistake you can make with one.
- Listing price vs sale price
- A listing price is what a seller asks. A sale price is what someone actually paid, and it's usually lower. Most prices you see online, ours included, are listing prices, and we always say which.
- Spares or repairs (not working)
- The seller is telling you it doesn't work and they won't take it back. Only for people who know what a repair will cost. If that's not you, walk on.
- Swiss Made
- Printed at the bottom of many dials. It means the movement and final assembly are Swiss. It's a sign of origin, not of quality or authenticity on its own.
- Accuracy (seconds a day)
- How much a mechanical watch gains or loses each day. A healthy vintage watch keeping within half a minute a day is doing fine. A few minutes a day means it needs a service.
- Homage
- A newer watch designed to look like a famous older one, sold under its own name. Perfectly legal and often good value. It's not vintage, and it's not the watch it resembles.
