Minerva round waterproof Shock Resist
Excellent all steel case screwback case measures 37mm long lug to lug by 31mm diameter. Good original dial with some darkening on the edge between 9 and 10:00. Good original crown, replacement acrylic crystal. 17J manual wind movement sets and winds perfectly, keeps time to within 2 min/day but not known when last serviced. Used but serviceable 16mm black smooth leather band. Minerva is known mostly for its chronographs, but the company also made time-only wristwatches. They are fairly uncommon; I can't even remember the last Minerva like this that I offered for sale.
