We have threads for what we’re wearing now, a G-Shock thread, Divers watches and so many others. What do you put on when you have some work to do and need something tough. These are mine, I’m currently wearing the Timex now. I work in HVACR and I get into some nasty places and have scraped concrete walls crawled through more dust and mud than I want to remember and been in 130° attics covered in insulation and these have made it so far. Show me what you got.
