Most all of the Grahams are are very acurrate, but the best of them are probably the V2 Diver models. The V1 Diver is a nice watch as well, but the dial on most of those models is missing hash marks for the minutes at 29 and 31. It's a pretty obvious omission, so stick with V2.
The big issues with the Graham reps isn't acurracy, but quality control. The triggers aren't anywhere near as well made as the gen Grahams, so be sure your dealer inspects and tests the trigger housing throughly. Have him make sure it's not loose and floppy. The Swordfish movement (even the hi beat one) uses a module to move the minute counter, so your dealer should test the movement thoroughly before posting.
If you like the Classic Oversize models better than the Diver, I would stick with the V1. The AR is better on the V2, but the V1 is more acurrate overall. Also, and more importantly, the trigger on the V2 will scratch the back of your arm and drive you out of your mind. I couldn't stand to wear mine for more then 20mins without having to take it off. In contrast, the V1 is very comfortable. So for the Classic models, stick with V1. They're cheaper too.
If you like the Swordfish, be sure to get one of the ones that has the high beat 28,800 vph A7750 movement. Do not go ANYWHERE NEAR the models with the low beat 7750. The lo beat 7750's are generally hit or miss quality wise, but the ones they used for the Swordifsh are notoriously bad. I sent one back to the dealer 3 times for repair and still it never worked. It finally got lost/stolen in transit the last time I sent it back, and I was actually happy to see it go. Most of the hi beat Swordfish models have Serial #1893 on the caseback. Have the dealer check the movement on a timer to guarantee you're getting the high beat.
You can get the four "Ranger" models for a good price from Toro. The AR isn't great and the dials on some of them (yellow and white) have some minor flaws, but they're nice watches with hi beat movements for a great price. They have been sitting around for a while (hence the closeout price) you could get a "bad" movement, but Toro will replace it for you if you're willing to send it back.
There's also the four RAC Trigger models out there, but few dealers are stocking them. They have a lo beat 7750, but the two I own have been fine. It's not a 1:1 rep. There are some minor issues: dial doens't quite have all the sharp details of the gen, the date magnifier doesn't really have much mag, the AR isn't great, etc. But I really like mine. It's comforatable and well made, and looks different from all the other Graham reps out there.
Of course, avoid all the crappy quartz and A21 jewel reps. They're all a joke.
Hope this helps.
