It is not by Timex. I saw a listing for a Timex Sportsman Wearever watch. Very fuzzy picture but it was in a Timex case. Since I like collecting cases I figured why not for $8.50 total. Packaged arrived yesterday and sure enough not a timex but it is a mercury.
Diod some quick searching and what I gather is this is one of those watches made from parts from differnent makers. this is a common pratcie in the industry from what I've read. Anyhow, the movement Swiss Made 17 jewel by Avia.
Cleaned up, new crystal, new strap and a nice additon to the collection. I'm thinking early to mid 50's based on a case size of just over 31mm. Will be taking this to my watch maker to ask him more about it.
