    Hello,

    I bought a beautiful rowing stopwatch but can't understand how to read the dial. I read descriptions in Heuer catalogs and it seems, it helps to count number of strokes.

    0-10 mn register
    1/10 sec recorder (1 revolution in 10 sec)
    ref is 403.914

    if some have any idea

    Best regards

    OK, I think, you would time 4 complete strokes. Say that took 8 seconds, which would equate to a stroke rate of 30, the large, black chrono hand would be pointing at the black 8, which lines up with the red 30.

    Have you tried running it yet. Do the black numbers represent seconds?

    You are correct. It’s my favourite chrono although completely useless to me. It took me a long time to figure out. The black numbers are indeed seconds. Seeing that sweeping seconds hand going round is pure joy. The small hand counts 10 seconds increments. So each time the large hand goes round, the small hand shifts by 1 submarker. ‘1’ represents 1 minute.

    Excellent. I'm a former rower so it makes some sense to me and I'm glad I interpreted the dial text correctly.

    Frequency/min is obviously stroke rate but the Base 4 had me foxed for a bit until I realised that it referred to the number of strokes to time.

    It's a bit like doctors and nurses taking your pulse but only timing it for 15 seconds. The watches they use then tell them your pulse in bpm.
