Tag Heuer Carrera Chronograph Servicing

As a Tag Heuer Authorised Workshop we are approved to repair Tag Heuer watches. We are able to order parts direct from Tag Heuer to repair almost any fault – from a broken glass or crown through to parts needed to repair the movement.

This job involved working on a Tag Heuer Carrera Chronograph which arrived to us in well used condition. From the condition of the case it appeared to be our client’s daily wear watch. These watches are absolutely meant to be worn, so some aesthetic wear is to be expected.

On arrival the automatic winding was not working and putting the watch on our timegrapher showed it was not in good working order.

The movement – a Tag Heuer calibre 16, based on an ETA 7750) – was in desperate need of a service. The reversing wheel, part of the automatic winding mechanism, was thoroughly worn out. This needed replacing during the service alongside a few other components.

Servicing the movement involved completely stripping down the Calibre 16 automatic chronograph movement. These are excellent movements and the base calibre is used in many high quality chronograph watches. Everything is checked and cleaned by hand, before being put through our watch movement cleaning machine. Reassembly and oiling can then take place. We use a variety of different lubricants and oils based on the part and function. We adhere to the manufacturers specification for this, as given on the movement data sheet.

Once the movement is serviced, we can begin complete reassembly. We reunite the movement, dial and hands with the thoroughly cleaned case. We can then pressure test the complete watch for water resistance before it goes on test prior to collection by our client. A job well done – this Tag Heuer Carrera Chronograph is back to excellent working order after this intervention.

Yours sincerely
