I was going to title this The Magnificent Seven, but when in Rome, err Japan...
Over time I've been lucky enough to acquire 7 MR-G's so I figured I'd show the whole group together. There are a few models I haven't acquired, time will tell if I go over the 7 mark. The first MR-G's were released in the late 90's, only produced for 5 years or so, and only sold in Japan. They were Gshock's first foray into all metal watches and most were available in SS or Ti. They have the same water resistance and shock resist attributes of any other G and came in digital, anadigi, and analog varieties. Yes, because they're metal they can scratch, so if that bothers you, they aren't the best for rough and tumble activities. I mainly wear mine to the office. I focus on the titanium versions because I like the color and weight vs. stainless. The crystals are domed slightly unlike G's of today. Relatively expensive compared to other G's of the time, the least expensive being around $350, some in the 4,5,6 hundred range, I'm not accounting for inflation. Nowadays, they can be found for a fraction of their original cost, which is great for me because I'm thrifty (cheap).
As you can see most have a rubber ring on the caseback, some have a couple of rubber guards, all of which can be removed if you don't like them. I suppose they are there to help keep the watch from sliding around, but also to prevent the bracelets from rubbing against the back of the case when handling them. Some have slightly different bracelet link styles and some versions have an engraving on the clasp. From the side you can see that they have very similar designs elements.
Here they are individually in no particular order:
1000T This one has a name unlike the others, the Tactician.
131 Interesting to me that even though this is titanium it just has "131" on the caseback, not "131-T"
The early MR-G's came into being about 15 years after the first Gshock, and are an important part of Gshock history. Of course, the MRG line is still around today but they aren't as interesting to me. They have a nostalgic quality about them, but are also timeless in my opinion. Yes, they may not be solar or atomic, but their simplicity is part of the charm. The build quality is amazing, I wonder sometimes if they were discontinued simply because manufacturing costs were to high. I really can't recommend them enough. After all my other G's succumb to resin rot, perhaps after my time is up even, these Seven Samurai will be still be magnificent.
