I've always had an interest and a need for stopwatches in my coaching and training. We time pieces on machines or on the water all the time.
Always digital...
That said, I have taken an interest in older mechanical stopwatches. I own about 17 at present. Tick, tick, tick, tick....
They come in many varieties: 100/60/30/10/3 second dials. Some measure single seconds, others 1/5th, 1/10th, and even 1/100ths. Some have a split timer hand. It's all good.
Heuer, Breitling, Smiths, Leonidis, Jacquet, Wakmann, Minerva, Elgin, etc. I also own a Russian Slava, which is BIG and well made.
According to my wife, a little safer than my 540+ hp Infiniti.....
