Seiko S-261 Snap-Back Case Opener

During my first trip to Hong Kong back in 93, I saw a version of this tool made by a German company. About a year later Seiko came out with this tool at half the price of the German model. Now everybody can open the back of snap-back cases without scratching the backside case or cutting into the coil. However, the openers blade can dig into and notch a soft gold case. It is best to use this tool on harder metal cases.




Seiko Case Holder S-212

For use when opening screw back cases. Rubber suction base hold firm and is ideal for desk/counter top use. Can hold cases from 22 - 70 mm.

Now you can recharge your customer's power capacitor instead of replacing them. Seiko has developed a charger to charge SEIKO KINETIC watches. Depending on the model an out-of-power watch can be recharged in 5, 10, 15 and 30 minutes. Every shop needs one of these chargers, and it also makes a good resale item to collectors who cannot wear their KINETIC enough to keep it fully charged. The dimensions are 5 1/2 x 5 x 1 1/2.
