Hi All, On the verge of purchasing the following https://imgur.com/a/GsFcJwc Barly any info except the following: I purchased this February of 2017 from a seller on eBay with great feedback. I can provide their seller information if needed. He said that it was serviced January 2017. I wore it for a few months, but stopped because I was worried of damaging it. The seller listed it as ref. 136.005 cal 610 and believed it to be a 1964 model. It is currently on a black leather ColaReb strap that will be included. On the verge of buying but very new to this game! Any advice would be welcome!
