I forgot to mention... I have two curved straps coming from Ivan at Two Stitch... I asked for them because my Explorer's case is so sharp that it scalps the top of all of my leather straps.
I like the look of bracelets on some watches but find them uncomfortable to wear - so its straps for me.
I have a fondness for Hirsch and have a few hand made ones, my favourite though is the Di Modell Rallye. Very comfy and durable at a great price. I alternate between these and Velcro or Perlon.
I sold the bracelet that came with my Speedmaster without even trying it on. It looked way to chunky and the lack of adjustment was very poor.
i keep my GMT Master on a bracelet except to play around on a perlon strap from time to time. im working on getting a handmade leather and canvas strap for the Railmaster which was always the plan for that watch
