When all the technical drawing confirmed, we start tooling, usually it takes 30 days to get rough shaping, we also call watch case blank. Then we use NC machine to get the accurate space for movement, glass, lug top and bottom etc.
For the un-regular shape case including square case and all kinds of special area like dial ring positioning, bottom strap fitting etc request CNC milling.
This is a process of get the lug holes for strap, and holes for crown tube. We request strap or bracelet when we drilling the lug holes to secure perfect fitting, if anything is changed during sampling and mass producing. We need client informs us in advance. Especially for the solid end piece band. Sometimes the sample band has different tolerance with mass production. Hence we need a close communication with our partners or clients.
