Hi all,   I've been on the lookout for a Tissot T-12 with a screw-down crystal retainer for some time but they're usually priced a bit out of my budget at USD200+. It was a 'nice to have but only at the right price' watch.   A few weeks back I spotted this T-12 on eb@y at a buy-it-now price of USD55 and USD10 for shipping, didn't hesitate to pull the trigger! Great price but needs some work... a new crystal and crown required and most likely a new crown tube. The tabs holding the movement in
