My 18mm Meyhofer silicone armband for my 19mm wide Longines Hydroconquest has arrived. I popped it on first thing, and here are some pics with my impressions.
1. This armband is comfortable. Unlike some other rubber or plastic (I guess) armbands I've purchased, this conforms to my wrist immediately.
2. My Hydroconquest looks great on black. Blue and black are the perfect combo.
3. I had an Eulit perlon that I wore the watch on for a while, but it was just too thin and always looked a bit off. The Meyhofer is the perfect thickness.
4. Unlike the perlon, this armband has designated holes for the clasp. I actually prefer this. I can adjust when my wrist grows or shrinks much easier. With the perlon, I was always fumbling around trying to poke the clasp into the proper place. The metal bracelet had no adjustment on-the-fly whatsoever. Only micro-adjustments, which I was never able to get to the proper size to be comfortable for me.
5. I noticed it when the watch was on perlon but, without the bracelet, this watch is light. I don't like heavy watches, and the metal bracelet caused the Hydroconquest to weigh in around 210 grams. Which was often noticeable, especially when my wrist shrinks due to cold and the watch dangles a bit. On the silicone, this watch weighs in at a featherweight 94 grams. That's a lot of bracelet weight.
6. That clasp is T H I C C. But it doesn't dig into my wrist or anything, so okay.
7. The fact that the armband is 1mm too narrow is noticeable, but not too bad. Right now, it doesn't bother me. We'll see how that goes. As folks here have suggested, I can always get a 20mm and shave down the bit at the lugs. Right now it's fine.
First impressions overall: I'm content. And Meyhofer silicone bands are a great deal at just under €20.
