Vintage watches attract a lot of folklore. Some of it comes from a cousin's uncle who "had one once." Some comes from forums at 2am. Some of it is half true, which is the most dangerous kind.
Let's go through seven of the most common myths and sort out what's real.
Myth 1: "Old means unreliable"
The myth: A watch that's 50 years old must be on its last legs, and buying one is basically adopting a very small, very expensive problem.
The truth: Age on its own tells you very little. Plenty of vintage watches were built to be repaired rather than thrown away, with simple, robust movements that watchmakers have worked on for decades. A well-kept watch from the 1960s can outlast a lot of modern gadgets.
What matters is maintenance, not birthday count. A serviced, looked-after watch can be a faithful daily companion. One that's been sitting in a drawer with 40-year-old oil is a different story.
The catch (we're honest like that): Vintage watches do need servicing every so often, usually every five to ten years or so, and parts for rarer models can be hard to find. That's why we nudge beginners toward common, well-supported movements.
Verdict: Mostly busted. Old isn't unreliable. Neglected is unreliable.
Myth 2: "Water resistant means swim-ready"
The myth: If the dial says "water resistant," go ahead and jump in the pool.
The truth: This is the one that costs people the most money, so please read it twice.
Water resistance isn't permanent. It depends on rubber gaskets and seals, and those dry out, harden and crack with age. A watch that was water resistant in 1972 may have lost that ability decades ago, unless the seals have been replaced and the case has been pressure tested.
"Water resistant" on the dial isn't a promise today. It describes how the watch was built, not its condition now.
Low ratings mean splash-proof at best. A watch marked 30 metres is about rain and hand-washing, not swimming.
Crowns matter. A push-pull crown is far less protected than a screw-down one, and a crown left pulled out is an open door for water.
Hot water and steam are the enemy. Showers can sneak moisture in even when a cold dip would have been fine.
Verdict: Firmly busted. Treat vintage watches as splash-resistant at most, unless a watchmaker has recently tested them and says otherwise. If you want to swim, a modern dive watch or an inexpensive quartz beater is a much better plan.
Myth 3: "Mechanical means inaccurate"
The myth: Mechanical watches lose minutes every day, so you'd be better off asking a passing stranger for the time.
The truth: It's fair that mechanical watches can't match quartz. A cheap quartz watch will beat almost any mechanical movement for raw accuracy, no contest.
But "inaccurate" is a stretch. A healthy, serviced mechanical watch typically keeps time within a few seconds to a few tens of seconds a day, which is plenty for real life. It also has quirks:
Position matters. A watch can run slightly differently lying flat overnight than on your wrist.
Wind level matters. A fully wound watch often keeps better time than one running low.
Condition matters most. A watch that gains five minutes a day isn't "being mechanical." It probably needs a service or regulation.
Verdict: Half busted. Mechanical watches aren't as accurate as quartz, but they're far better than the myth suggests.
Myth 4: "Winding it too much will break it"
The myth: Wind a hand-wound watch one turn too far and snap, there goes the mainspring.
The truth: Most of the fear here is leftover advice from older, cranky mechanisms. In practice, a hand-wound watch tells you when it's full: the crown gets firmer and resists. That's your cue to stop. The damage usually comes from people forcing the crown past that resistance.
A gentle wind each day, stopping when it feels snug, is all it asks. And don't wind it hard while it's sitting at an odd angle on your wrist, where you can put a bit of stress on the stem.
Verdict: Mostly busted. Wind it gently, stop at resistance, and you'll be fine.
Myth 5: "Automatics must be worn every day or they'll die"
The myth: If you don't wear your automatic daily, it'll seize up in protest.
The truth: It'll simply stop. That's it. When you pick it up again, give the crown a few turns, set the time and carry on. There's no harm in a watch resting between wears.
In fact, a watch that never runs for years can suffer from old oil going gummy, but that's a matter of long neglect, not a weekend off. Wearing different watches in rotation is completely fine.
Verdict: Busted. Your watch is not sulking. It's just asleep.
Myth 6: "Magnets ruin watches"
The myth: Put your watch near a phone, a speaker, or a fridge magnet and it's done for.
The truth: Magnetism is real, but it's rarely a disaster. A magnetised movement usually runs fast, because the hairspring coils start sticking together. It's one of the quickest and cheapest problems for a watchmaker to fix, using a demagnetiser that takes minutes.
It's worth keeping your watch away from strong magnets, like magnetic phone cases, speakers and magnetic bag clasps. But if yours starts running oddly fast, don't panic. It's usually a quick fix.
Verdict: Half busted. Real, but easy to sort out.
Myth 7: "Cheap vintage is junk, and a shiny polish is always better"
The myth, part one: If it didn't cost a fortune, it can't be any good.
The truth: Some of the most dependable, charming vintage watches are the everyday ones. They were made in huge numbers, which means plenty of watchmakers know them and parts are easy to find. Price tells you about demand, not quality.
The myth, part two: A freshly polished case is a better case.
The truth: A light polish can freshen things up, but heavy polishing removes metal. It softens crisp edges, rounds off bevels and can make a case look a bit melted. Many collectors actually prefer honest wear to an over-polished case, so it's worth asking whether a watch has been polished, and how much.
Verdict: Busted on both counts. Affordable can be excellent, and shiny isn't always better.
So What Should You Actually Take Away?
Vintage watches are neither fragile antiques nor indestructible tanks. They're well-made machines that reward a bit of understanding.
Look at condition and service history, not just age.
Treat water resistance as something that has to be checked and maintained, not assumed.
Expect good, not perfect timekeeping from mechanical movements, and enjoy the character that comes with it.
Wind gently, keep magnets at a distance, and don't worry if it rests between wears.
The Bottom Line
Most vintage watch myths come from one-off bad experiences or from assuming old watches behave like old phones. They don't. A watch with a decent movement and an honest history can give you years of enjoyment.
At CM Timepieces, we tell you what condition a watch is really in, including any quirks, so you can enjoy it without nasty surprises. If you're unsure about a listing, or want to know whether a particular watch is fine for daily wear, message us. We're always happy to help.
Happy hunting.
