The 1945 Tudor Oyster project described here left the watch essentially finished but for a somewhat loose domed acrylic crystal.

I had purchased a small selection of 27mm domed acrylic crystals in the hope that one of them would fit snugly, pressed into place with the aid of my trusty crystal press.  However, ‘hope’ is simply not good enough when ‘doing it properly’ is required and so I returned to this one armed with a new 27.2mm acrylic and a freshly purchased crystal lift.

The idea here is that the crystal is first placed face down onto the sizing platform, over which the jaws of the lift are placed.  The knob on top is then screwed down until the teeth grip the edges of the crystal.
