Rolex

Day 1 of the weeklong swap with my friend’s Explorer II 216570. I put it on a NATO that draws out the orange in the GMT hand. Although I have several NATOs, the color on this one makes for a very sporty style that’s new to me. I’m liking it so far. ...  

..it screams, "See me, want me, love me!"

Best wishes Alkiro

Try it on an Isofrane and you'll never find a more comfortable sport watch

They don’t make a 21mm strap, but I’ll try them out for other watches for sure.

I had one on my explorer II 16570 and it was magic. Maybe a rubber B?
