Sorry if I came across harsh or [just my usual asinine] - I primarily bop in here once a week or so and see if there is anything I can join in on. Batteries are problematic, especially older ones since the numbering systems often made little sense. That is a nice watch. I've had those but for the life of me I don't remember what they take so I'm not going to over-extend myself. But I wanted to [hopefully] bring a little clarity to what you were working against in both diameter and thickness.
Re: Over-extending yourself. Want to get filleted? - mis-speak on a forum.
