Let's read good G-Shock literature while enjoying a rare and unique beer.
The bracelet looks pretty sophisticated, but sizing is relative easy. All you need is such a bracelet tool or maybe even only a pin. You need to push the pushpin that far, so you can move it out of the link.
No doubt, the bracelet gives the watch a pretty tough look. Although the bracelet has a kind of metallic look, it is a so called “Metal Core” bracelet. The big outer links are made of black resin, while the core of the bracelet consist of metal links, providing maximum strength in the bracelet, while being very light. The pushpins fall into metal reinforced holes of the resin links (see third photo in the above series). To provide maximum comfort, the GW-M5600 model is the slimmest of all 5600 series watches, so it can slip easily under sleeves of shirts under jackets at the office.
According Casio does the watch with a full bracelet weighs just a little more than 100 grams, much less than a full metal bracelet. In real it is even lighter, and after adjusting the bracelet (I removed only 2 links) it weighs just a little more than an average G-Shock. Although it looks hard to remove the links of the bracelet, it is actually pretty easy. Just try to remove equal amounts of both sids of the clasp so it stays on the right place under your wrist. Very nice is that the bracelet can be adjusted in 4 positions at the buckle. This made it possible for me to only remove two links, instead of the usual three. The 4 positions span about one link in length. In chose to put on an extra link and put the clasp on the first hole, instead of the last one.
Tiktox, UK, who has them for £149.- (€187, $240). This is a much better price than what you probably will pay in Japan, as this model comes with a suggested retail price of ¥24000 (€240, $308), though you can find this model also in Japan for just above €200 ($260) if you look good. Although the GW-6900BC has the same suggested retail price in Japan, you should expect to pay around €230 - €250 ($300 - $325) for this model. It’s only available in Japan at the moment (a small amount was sold in the UK in the past). The look of the watch is different from that of a regular model with resin straps. It seems the look of the bracelet add quite on the look of this watch. I think it won’t look too bad for formal occasions. There is maybe only one thing I would loved to have seen extra on this watch and that is the EL Afterglow. Afterglow is the time between pressing the light button and the light turning off again. Where you can choose on most modern models between 1.5 and 3 seconds, on this model the light already turns off at 1.5 seconds. I would have been more happy if the Afterglow would had been 2 or even better 2.5 seconds. Overall, I think the GW-M5600BC is a great watch with good looks, specially with the good detailed light weight bracelet.
