How Often Should You Really Service a Mechanical Watch?

"Every 3 to 5 years" is the standard advice, and it's a reasonable default — but the honest answer depends on how the watch is worn, how old it is, and what's inside it.

What actually wears out

A mechanical movement has dozens of tiny pivots turning inside jeweled bearings, all relying on a thin film of lubricant. That lubricant oxidizes and dries out over years, whether the watch is worn daily or sitting in a drawer. Once it thins out, metal starts wearing on metal — slowly at first, then faster.

Daily wear vs. occasional wear

A watch worn every day accumulates more dust and moisture exposure but also gets more consistent lubrication distribution from motion. A watch worn occasionally can actually see its oils dry out and gum up faster, since it sits still for long stretches. Neither extreme is safe from the calendar.

Vintage movements need more attention

Older calibers generally used softer lubricants than modern synthetic oils and can benefit from a shorter interval, closer to every 3 years, especially if the watch has any history of water exposure.

The cost of waiting too long

A routine service — cleaning, oiling, and regulation — is inexpensive compared to repairing worn pivots, a scored mainspring barrel, or a damaged gear train, which is what eventually happens when dry lubricant turns abrasive. Catching it on schedule is always the cheaper visit.

Not sure where your watch stands? Bring it by the bench — a quick inspection tells us exactly where it is in that cycle, no guessing required.
