    How to trim a rubber dive band

    I have a luminox ANU that I wear on a nato and would like to change over to a rubber strap preferably an isofrane. How difficult is it to trim like a 24mm down to a 23mm which the ANU is. I’ve used a razor knife on leather with good results but of course with the price of an isofrane I would like to know the best way to go about it. Thanks in advance

    Have you tried squashing the strap in place before cutting it.

    Perhaps curved spring bars trick might help. I successfully used them to fit a thick 21mm strap into a 20mm watch so might work for you. I’d try that before getting out the razor. Also I would get a Borealis ISO strap to start with. It’s a less expensive experiment than Isofrane and still quite nice.

    I ordered a Bonetto Cinturini 24mm and I’ll try to squeeze it in before cutting

    A hot ( 3-400 degrees , not red ) sharp knife with the rubber slightly streatched , cut fast using a straight edge eg. steel ruler or the likes and the cut will seal as it cuts . We use this technique to cut small rubber belts at work and if done right the cut will be perfect , just remember Sharp and hot ish .

    Check YouTube. Good videos there on how to trim out a rubber watch band.

    Good luck.

    Thanks to all for the suggestions . I ended up buying a 24mm Benetton that Holden’s puts out. Looks like the band on marathons and it squeezed in without an issue

    I think a dremel grinder would work
