Same. Out of my entire collection, the 5610 gets the most wear because for me it is the perfect watch. It is so rugged, I can keep it on while wrenching on cars and it still looks fine after several years.
I feel the same about by GW-6900. I have other watches, but I wear that one 90% of the time. No worrying about batteries, no worrying about me being a clumsy git, and it's always accurate.
I have the GW-M5610BC! Got it vs the standard 5610 for the negative display that makes it look like Darth Vader's watch. This is indeed the perfect watch. I love it.
