After wearing the GW-M5610 for a couple months I decided I might be a G-Shock guy after all so I decided to get a round model to go along with the square. After a lot of research I narrowed it down to the GW-6900 and the GW-2310, and it really wasn't a contest, the 2310 won hands down based on appearance alone. I just can't convince myself that I like the three eyes on the 6900 even though I know it's a classic. I've also read that some guys don't care for the shiny metal on the 2310, but I really like it. So, I started watching the eBay and the sales forum here hoping to find a decent used one that I could try, and if I didn't like it I wouldn't be out much money. I found a seller on the bay that had several available for $45.50 with free shipping so I ordered one.
It arrived today and it looks to have been worn very little, it is in excellent shape. All of the color in the lettering is still there and no real marks anywhere on the watch so I lucked out and got a good one. I wore it cutting the grass and it is very, very comfortable even though it's a bit bigger than the 5610. I've only worn it a couple hours but I think it's a real keeper that has earned a spot in the rotation. It has a J date code so it was manufactured in 2010, and it was made in Thailand. For a five year old watch it has very low mileage on it I believe.
One thing I did notice right away was that the buttons are a little easier to push than the 5610. I turned on the auto EL function and it seems very sensitive, much more so than the 5610. It comes on with the slightest movement of the wrist and it is a bright, sunny day.
Here's a couple shots of it. Enjoy!
One thing I thought was kind of cool is that it synched up with the Mother Ship at 2:04 AM while it was somewhere between New York and Indiana on it's way here, presumably in a USPS semi because the tracking showed it arrived at the post office at 8 AM today.
