I make my own straps, started 15 months ago, I aim for good but mostly end up at good enough. These straps were made from 1.0mm thick saffiano leather with Zermatt leather lining.
Just had my 20368 Polerouter serviced. Deciding on a padded (3mm) vs non-padded (1.9mm) lizard strap. I'm curious what you're wearing there and which you think would look better?
