Watch Assembly Procedure

All incoming goods are counted and the quantities are compared with the delivery note. Upon request, we can conduct a 100% visual inspection of all your dials, casings, case backs and crowns on reception and issue a corresponding inspection report. 

Following acceptance, our watchmakers assemble a sample watch so that technical data, such as stem length and hand height, etc. can be determined. At the same time, the components are unpacked and placed in individual internal transport containers to protect them from dust.

Customers can determine the provisional delivery date as soon as a job order has been initiated.

Following removal of the working hands from the movement, the dial is placed manually. Next the hour and minute hands, the chronograph hands and centre hand are correctly fitted using a semi-automatic Lecureux line. The height and the correct position of the hands are checked using a display. With movements manufactured externally and smaller ranges this is done by hand.

Watch glasses are cleaned with compressed air and vacuum; following this operation, the individual watches are cased by hand. The case back is closed either using an electric screwdriver (individual screws) or using the Roxer machine for screw-down backs.

All assembled watches are checked for water resistance, regardless of batch size. The maximum test values are 20 atm. / 200m. - At a premium charge, the watches can also be checked in real water at max. 30 atm, including water condensation.

Watch water resistance

All watches undergo at least a 48-hour check for good working before they are readied for shipment or strap assembly.

The various watch straps, made from leather, rubber or metal, are fitted using specialist tools.
A QC team checks all watches 100% for aesthetic defects, rejecting the ones that are not up to standard. Faulty watches are reworked and inspected again.
