After servicing
This Longines watch model: L4.721.2 was sent in for servicing because of bad timekeeping. Looking at the timegrapher's reading before servicing shows that the watch is running slow at 201 seconds per day. The amplitude is only 159 degrees  and beat error is 8.2 milliseconds. After overhaul and oiling, the timegrapher's reading improved drastically. The accuracy is +1s/d, amplitude back to normal at 269° with no beat error.

Seiko Kinetic To Replace Winding Crown


One of the common problem with older Seiko Kinetic is poor water resistant of the winding crown and the push button. Most of these watches sent in for repair have rust built up inside at the push button and winding stem. This Seiko Kinetic 5M43-0F20 was sent in to replace the broken winding crown.

Cerruti 1881 For Repair


This Cerruti 1881 Dress watch was sent in for repair because water has intruded into the watch. Water got in through the worn out winding crown and rust has started. When water condensation is seen beneath the watch crystal, quickly send it to a watch shop. Don't assume the water will dry up by itself as it won't, but instead will rust the watch movement and costs more to repair.

Omega Speedmaster For Repair







 This Omega Speedmaster Caliber 1151 was sent in for repair. Water has intruded into the watch and it has already stopped working. Upon checking, rust has already started to build up. Luckily it was sent in before any big damage to it's movement. After repair and calibration, the reading on the timegrapher is good and it is water-sealed and tested.
