Has anyone trimmed the lug width of a rubber strap?
I have a seamaster midsize and been looking for a decent strap. I've thought about buying the fitted seamaster style like posted above and trim the width. Since it's fitted I'm not too sure I can make it look "original"
I have done several, and there's a.. learning curve,
until you're sure, keep working on old straps you don't mind destroying.
this is something I do/ have done for watches with proprietary lug designs, like oris,
but for a difference of 2 or 3 mm from strap to lug, I fit them directly,
I even prefer it like that, as it adds a nice curve and often helps balancing the watch.
I don't know what strap you're referring to, exactly,
but fitted straps usually have a plastic or metal insert at the ends attaching to the watch, and that is impossible to cut,
don't even consider it.
also, the hole placement for the spring bar in relation to the watch head will likely not be correct (too close/ far/ high /low) and it's distance to the top of the strap can't be disguised if incorrect, only a mm or two extra thickness on the underside may work.
on a midsize, it's easy to find a strap with generic lug fitment that'll be thick enough to cover the gap, if that's what bothers you,
maybe you can even find an aftermarket option and Omega has been toying with small sizes lately,
these are the directions I'd take.
