What a full service is

The standard mark

“Service” means very different things at different counters. Here it means the same nine steps on every mechanical watch, and you get them in writing on the estimate.

  1. 1Inspect and estimateUnder the loupe, before anything is touched. Free, in writing.
  2. 2Take it apart completelyEvery wheel, bridge, spring and screw out of the case.
  3. 3CleanUltrasonic baths, then each part dried and checked again.
  4. 4Replace what is wornMainspring, gaskets, crown seal as needed. Quoted before ordering.
  5. 5Rebuild and lubricateSeveral oils and greases, each where the movement’s maker specifies.
  6. 6Regulate in six positionsDial up, dial down, and crown up, down, left and right.
  7. 7Test water resistancePressure and vacuum, where the case is meant to be sealed.
  8. 8Run for a weekOn the winder and on the bench before the final reading.
  9. 9Print the proofBefore and after readings go back to you with the watch.

The printout is the proof

The assay mark

A timegrapher listens to the escapement tick and draws how the watch is really running. We print it when your watch arrives and again before it leaves, and both go back to you in the box.

Example readings from a 1960s automatic, dial up. Our target for a modern automatic after service is between −4 and +6 seconds a day across positions, with amplitude above 270°. Vintage watches are regulated to what their movement can honestly hold, and the estimate tells you what that is.

Prices, before you hand it over

The duty mark

Every price includes the nine steps above and a one-year warranty. Parts are extra and quoted, with their price, before anything is ordered.
