If the choice were between those 2, it would be the DJ. As others have suggested, maybe you should look at a Milgauss or a 39mm Explorer.
I am not a fan of the current IWC products, which is a shame because I like several of their older pieces. Sadly, today most of their watches do nothing for me and I find their "Limited Editions" a really tiresome marketing exercise (so in general, I'd rather have a regular edition). They have so many limited editions, that I find nothing special about them at all....lets see off the top of my head they have or have had the Top Gun Miramar Edition, various St. Exupery edition watches, Cousteau editions, Boris Becker Editions, Prada Editions, AMG Editions, Darwin Editions, Galapagos Edition, and the Tribeca Film Festival Editions. While I think its great if a watch company supports various causes (by donating to them and sponsoring events), making numerous so called "Limited Editions" every 6 months or so, waters down the significance of a watch being a limited edition. I can hardly wait to see some of their next limited editions, .... next year there could be a 35th Anniversary Big League Chew Bubble Gum Edition, complete with a pink rubber strap (maybe they can make it smell like bubble gum), special presentation container consisting of a Big League Chew pouch and instead of a pillow or other item to hold the watch in place it could be wrapped in strips of Big League Chewing gum. Or perhaps with the 40th Anniversary of the film "Smokey and the Bandit" coming up in a few years they could have a "Burt Reynolds Smokey and the Bandit Edition" watch with a "Screaming Chicken" engraved on the case back.
I'm not completely against limited editions, but I think some companies over do it and its tiresome.
I just wanted to get folks thoughts on Omega's newish Mark II chrono - we always talk about the traditional Speedmaster, but I just tried on the Mark II at the boutique in NYC and it looked great on the wrist. To me, it looked like a really fun watch for the weekends and was so evocative of the 70s in a good way. I can get my hands on it for a great discount (~4k) and am seriously considering it. Wanted to do a sanity check re: others thoughts before I did something rash.
I think its a fun watch. Perhaps I'd look into the availability and cost of an original, before deciding to go with this one, however, it seems like a good watch for a very reasonable sum. I know there are many things from the 70's that are best forgotten...but I do think some of the 70's watch designs are very cool. Wishing you luck with whatever you decide.
