hi, my father also own this chrono 6138-0011 and i think he bought it somewhere in 70s.. i still remember how he struggling to get it repaired.. so he left wearing nite market watches.. and deep in mind one day to buy for him the replacement.. so after start earning and got married, i bought for him a diver 7s26-0020.. and he was so happy..
now he passed-away, few months back my mom gave back the diver to me since i'm the one who bought it for him, still in very good condition even already after >10 years.. thinking to give some different look so google around for rubber strap.
so, remember this chrono and start google around, wow!! immediately ask my mom where the chrono.. so last month i found this chrono in one of the boxes.. this chrono is very rusty but i determine to restore it whatever it takes.
so now, in progress, the dial total damage but the hands look ok.. so i have to replace the dial.. looking at ebay and found one.. after bidding won it total won including post RM76.. then while looking at muday.my found this look old dial but different from one from ebay.. seller said original taken from watch.. but asking around at watchuseek but they said both aftermarket.
no patient to wait delivery from ebay, i decided to buy this dial from mudah.. thinking to buy spare parts from watches but the price too high in ebay.
try to nego but the seller refused.. rm100.. so this watch guy, each of part he bath it with kind of oil/chemical for few days to remove the rust and fungus.. he said the crown stem too rusty and damaged but he can replace it original taken from his 6138 spare parts.. the crystal surprisingly look good and clear after some cleanup.. the bazel still in good condition.. only some very tiny scratches.
currently at reassembling stage.. i will try to update later..
