We are Bruno and Eng, partners at [https://www.instagram.com/eng\_watches](https://www.instagram.com/eng_watches) *Our previously reddit account with* ***149 Transactions*** *was locked out due “incorrect username or password”. Since it’s been a few month trying to get it back, we decide just to create this another one instead.* Up for sale this classic, vintage Citizen "Challenge" diver. Everything looks good with expected signs of use for its age. A few marks on the bezel and patina in the hands and indices. Looks like it has been lightly polished. I have no service history, but the watch is working and measuring at about -18s/d. Comes with a brown silicone strap. Please consider looking more the images on the post for more details — which you can download or zoom. Approximately dimensions: 40mm, 47mm lug to lug, 20mm lug width, and 13mm thickness.
