While looking for an alternative to the bund I was using on my custom Seiko BFS I came across the Maratac Elite Series Composite Straps.
They state: "It's like leather, it's like nylon, it's like composite. A regular strap doesn't work wet. This works wet or dry."
Stitched composite Watch Bands. Available in 20mm, 22mm, and 24mm, with black, white, red, or yellow stitching. All straps measure 24mm wide (non-tapering). Buckle side is 24mm x 80mm. Hole side is 24mm x 135mm. Straps are 3mm thick. Buckle is polished stainless steel. Weight 20 grams without watch. Comes with springbars. Contains no Kevlar™.

These sell for $20 and they flat fee the shipping which is nice. I bought a few of these in 20mm, 22mm and 24mm and a few Zulu straps and was only charged $5.15 for shipping and handling. Even more impressive their order team was enough on the ball that when I went back later that day to order two more things they found the first order and grouped it together and only charged me the flat rate on one order and refunded the shipping on the second order. This was done without me calling or asking in email so
When the strap arrived today it was exactly as described. The strap is uniform in width so all are sizes are 24mm wide and then are trimmed for the 22mm and 20mm for those versions. The thickness tapers from 5mm to 2mm which is really nice and makes it look like a very high cost strap. The strap comes with the spring pins (look to be 1.5-2mm) installed in each piece. All straps are black and as noted above there are 4 stitching color options (Black, Red, Yellow and White). They are really not very clear what it is made of exactly but it does have a leather with a rubber coating feel similar to some of the coatings. The look is a matt black with a diamond sort of nylon pattern with heavy stitching. The buckle is heavy duty Stainless Steel with a 4 mm center tang. The holes for the buckle are slotted to match the tang. The over all construction is very solid and I would believe a spring pin would break before this strap would fail. For the 20mm and the 22mm the extra kick out adds a nice touch on a Monster or a Tuna.
The BFS spring pin holes are 47mm apart so they are a little on the wide side. I mention this since one thing I see with all size variation is that the minimum wrist size this will fit while attached to the most Seiko watches is 7-1/4" wrist size (Maybe a 7" if you like straps looser) with out adding holes. Since these are slotted and not round that would be a little difficult.
So for the 20mm, 22mm & 24mm for 7" wrist and above and for less that a 7" wrist.
The feel is very nice and I actually like it as much or better than the one I have for my Panerai that cost 8-10 times as much. The look is exotic/high tech. It sheds water like a duck and can be tailored to the watch it is attached to by stitching color. I give it for feel, look, quality and value. Not bad when a $20 strap can look and feel better than one costing much more. So all as advertised on these accounts.
Overall I am really pleased with it and to prove it I have about 6 more coming in. Nice to have a strap that is both dressy and you can dive without changing it. Just what I was looking for.
Please note I have a 7.5" wrist and I generally wear the straps and bracelets tighter than most people do.
Please note on the above picture I tweaked up the lighting to show the texture and construction better. The thread looks a little brown because of this. Please ignore this, it is very black and matches the strap color.
