I've still actively use my Sony Smartwatch 3, as I haven't been able to find an similar alternative, which allows the screen to be removed from the strap.

Does anyone know where I can buy a replacement SW3 strap? Or does anyone have an old SW3 they don't need, or a strap?
My strap is getting a little worn, after wearing it every day.

Or alternatively, is there a more recent android wear watch, that has a removable screen, or can be mounted to a bike?

I remove the screen in my SW3 to take on MTB rides, clipping into a quarter turn (garmin) mount, like this: https://www.shapeways.com/product/38UUD775M/sony-smartwatch-3-quarter-turn-bike-clip?optionId=58417627&li=marketplace

I use the 'ghostracer' app on this watch.

Thanks
