Just received my custom GasGasBones ME2 strap this week...
ME2 ~ Black only for 19, 20 and 22mm lug widths
This is a nylon strap with velcro closure that is a play on NATO/ZULU styles; rather than sliding through spring bars the ME2 attaches like a traditional strap but is still connected underneath.
It's a very effective and rugged solution that can really enhance the look of a similarly styled watch. What's cool is that you not only choose your lug width (obviously) but also the lug-to-lug, as well as your wrist size, to ensure a perfect fit. I purchased this strap with my Magrette Moana Pacific Pro All Black in mind. Given these measurements the strap folds through the buckle and is exactly right.
Very easy to remove and put on, very comfortable. You can also select your preferred accent color for the stitching. Along the section that rides under the watch is a sewn GGB logo which is nice.
One option I didn't take advantage of was a nicer buckle. I'm just running a basic ring. In retrospect it would be worthwhile to choose a nicer buckle. That aside the quality seems excellent and presents an interesting alternative for your tool watches.
