Thanks - that means a lot coming from you :-).
I have worn the watch almost nonstop since I got it. A few additional thoughts:
Alarm is in fact louder than the GW-2500.
I changed the Nato to a two-piece Nylon strap but I'm still looking for something a bit thinner because there's not much space between the springbars and the case.
The watch is a perfect everyday watch with its low profile and IMO great combination of dressy style and functionality.
I haven't worn it while swimming yet but the 5bar rating should be sufficient for that - the manual says so, too.
One tiny flaw: the crystal is flush with the bezel and I managed to make a teenie tiny scratch in it while bumping the watch in a doorframe. Too bad it's not sapphire like on the LCW-M100. Might have to get that one, too - eventually .
