[Al Wyn]

Helped a neighbour to get a visiting friends car started late last night and clearly remember clonking said watch whilst doing so. This morning 6am i noticed that my watch is now minus its pressure release button anyone know if these are readily available? are they something i could buy and fit myself? cost of the now missing item?
