First off, I'd like to thank everyone for the comments they have made. For the most part they have been insightful and helpful.
But I think we may have moved off topic, and I fear this may be because I have not expressed myself clearly. What I wanted to know was if the extra outlay for the Bremont was worth it when the Damasko appeared to be a very similar watch. My question was never about the value of the watch. If all I wanted was value for money I'd wear my G-Shock all the time, instead of just when I'm at work. For the comments here it seems that the extra outlay would be worth it as Bermont have certified movements whereas Damasko don't (although I think they used to use DIN certified movements, I may be wrong on this) and the case construction and hardening appears to be of higher quality on the Bremont. I am a little put off by one of bylandie's posts which says there is a 40% markup by authorised dealers. This seems excessive but then again I don't know what the markup on watches like Omega and Rolex are so I can't really comment.
But again thanks for the comments (and feel free to add more) but I think I'll take the Damasko off the list and see what other day-date watches I can find.
