I have a question about the compatibility between Strap types within 19mm width ends.
Generally speaking - I have some issues with watches being too heavy or the straps making me sweat.
So, I have good experiences with using a New Gent (Black Rebel) with a Swatch Irony (Secret Agent) Strap.
To further reduce the weight I got interested in using an aluminum Strap - and I found one from the Diaphane Series.
They seemed compatible, because they all have the "3 Sgement" design with a 19mm end width.
But when I tried to fit it, I noticed that the axle diameter seems to be a little smaller and I stabbed the padding with the rod.
Am I doing something wrong? Are these even compatible? Is there an easy way to tell if straps are compatible?
