Hi  All.

I have a Aerospace GMT that could use a 4mm crown. The original needs to be replaced. It can be gold or silver, new or old. At the present time, I have an aftermarket crown installed, I have the old crown but the gasket is worn and I could not get it repaired.

check with "butchs watch guy" , he may have the correct crown BUT he does not sell parts, his parts are for his service customers. if your watch needs a new crystal, a cleaning or just needs to freshened up HE IS THE GUY! he does all our watches for the members of the forum. good luck, you have a NICE GMT, give it the best care!!!!!
