I own this, too, and used it as my only watch until a few days ago. Then the titanium mod for my GW-M5610U-1ER arrived by mail. I am wearing this now, but I wish it was as light as the LCW-M100TSE (which is 70g vs. 100g of my new one). Since I prefer pure digital watches which I grew up with I will stick to the G-Shock with titanium mod.

BTW, you forgot to mention that the LCW-M100TSE has a sapphire crystal, which is quite a unique feature in that price class. IMO it is the watch with the best value for the price.
