This is a specially modified Stocker and Yale Sandy 660 for Frank and Nick at CountyComm. It was fitted with an automatic movement and dome shaped plastic crystal. The movement has the desireable hack feature. Case is polished type, like a Rolex Sub. Despit the massive case size, it did not have enough clearance inside to make the automatic winding disc to rotate freely. My watchmaker found a solution by pressing the caseback inside so that it would stick out a little on the outside, thereby allowing the rotor to move around freely. Watch is winding properly and still manages to be water resistant. It's always a pleasure to see a second hand sweep!
