I just responded to a request of my experiences with my DC80-Black and it occurred to me that this might be useful to the larger community.
I've been looking at this watch alot lately. I just may need to pull the trigger. If you don't mind what are your pros and cons. Thank you for your time.
Okay where to begin ...
About color/style: I opted for the DC80-Black and I can say that after all these months, it still has that "new" look. It's an aggressive looking watch but somewhat less so due to the fine machining style of the bezel when compared to other bezels which have bigger teeth. I'd say the DC80 standard would be the easiest to adapt for most wear but given the choice I'd still go with the black. Of course I have other watches so I can switch over as per the what I wear for that day.
About wrist size: Mine is 6 3/4 and as far as I'm concerned it fits like a glove. Therefore, a wrist the same size, or larger, is optimal. Because the watch is heavy, I wear the standard strap that comes with the watch snug at the 2nd hole otherwise any possible sliding will be distracting. This is not a watch you can wear loose. A bigger wrist might help though.
About thickness: for an automatic chrono the thickness being just a little over 14mm is quite thin which impresses me. I can wear it under most of my everyday shirts. But to tell you the truth I've changed my habit as now, when possible, I wear my sleeve slightly rolled up allowing the watch to be exposed at all times.
About the bezel: Although one can opt for both the count-down and incremental, I am so happy I opted for the 12hr one. It not only does the GMT time-zone trick but it allows me to track multi-hour activities too. I've found that in real life being able to move the bezel in both directions is so practical to adjust for unexpected events when one is forced to change timing calculations. Try doing that with a digital watch! All the reviews are correct when it comes to turning it, there is no "accidental" twisting. I know I'll get flamed by this but if anybody really wanted to go "casually" diving I'd say this is one watch you can use, the fact that it is bi-directional is such a plus for me. It feels like the bezel will never get loose.
About the chrono: This is why I bought my watch. Having a central minutes chrono is such a magnificent no brainer choice compared to the standard tri-compax. The chrono is clear under ALL circumstances. Try tracking time when holding a log over your head and you'll agree.
About time accuracy: You know, I think a person could wear this watch for a month and not really notice any significant loss/gain of time. For me the watch does speed up daily but thus far we're talking about a couple of seconds over several days.
About setting the time: Unscrewing and screwing the crown is easy. I can tell by pulling on the stem that the watch is designed to have a date complication because there is an intermediate pull. Pull hard on the stem, and you'll hear it click, before you set the time.
General wearing: My watch is multi-purpose, I wear it everyday AND I depend upon it in the wilderness too. I travel alone and where I go it can be less safe than walking in a dark alley way in a seedy part of town. Therefore, I want to have the best equipment with me i.e. low tech and robust. So far I've been in mostly temperate climate so swapping the wrist band for a NATO is my normal habit. I'd suggest a rubber wrist band for the truly "humid" environments.
Servicing and Reliability: I am happy with my watch but it has been a work in progress. I've had to return it for servicing a couple of times. As far as I'm concerned this is new technology and because I'm in IT experiencing issues and bugs is something I see all the time. The great thing is that the service has been excellent. The watch is being improved continuously and everybody benefits when I bring up issues to Damasko, although I have been impatient getting the watch back.
Hope this helps in your deliberation.
