It will be absolutely the same with other mechanical watch

quartz is the only option to be honest

That's not necessarily true. Before you do or have anything else done to that watch, I would just see how it behaves after a standard cleaning.

I had an interesting case of a watch that was running fast due to rebanking when fully wound, due to a dirty mainspring. (Higher torque due to more friction, maybe counterintuitively.) After cleaning, it ran fine, including when worn on my R1150GS. Ditto for a Speedmaster and a Portugieser chrono, a 1940s Hamilton pocket watch movement (no shock protection!) I transplanted, and a variety of Chinese movements/watches. And of course my SKX011, but you'd expect that.
Your Rolex could be just a tiny bit dirty in the mainspring and a little high in amplitude, so that the bumps and vibrations when worn on the bike just push the amplitude over the edge (to rebanking) often enough to make a difference.

This is nonsense. Millions of people ride motorcycles with mechanical watches every day without issue.

Submariner has developed an annoying problem of gaining time when out on the bike. If not out on the bike the time keeping is perfect. It never used to do this so I'll be dropping it of at Rolex in Bangkok for a service. But just out of interest is this indicative of any particular mechanical issues? On a 900km ride (the roads were bad) it gained 12 minutes, on a 600km ride it gained 8 minutes. It's annoying having to reset the time daily when out for a while. Back to using the Speedy, CWC, Seikos or anything but the 14060M on the bike.

It's not entirely unrealistic from my experience.
I've had Rolex watches speed up a few seconds while out on a 1/2 hour run and they were outstanding timekeepers in every respect otherwise.

In contrast, my 2403 Co-axial is absolutely rock solid.

If you take a shower after your ride, it might slow it down.

200 miles on an Africa Twin it gained 2 minutes 20 seconds. Gained time on a CRF250 Rally as well. So that covers 1, 2, 3 and 4 cylinder bikes. Anyone have a Goldwing so I can try a 6 cylinder engine?

Yeah but you’d expect that from a brand like Rolex

Go straight to this V10…..

cut out the middlemen…or for ultimate smoothness a V12


if you still have trouble then you need this….48 cylinders you’ll be to busy hanging on to give a shit about the damned time!

I remember Seiko made these especially for riding motorcycles years ago

obviously quartz so they shouldn’t gain time,
They also did digital versions with the same angled dial, but they’d be too hard to read quickly whilst riding

MV Augusta 500-6, that's the job!
