To make you feel a little better some of that £45 will be down to the difference of 19% vat on stowa site and our 20% as well (about €11)
I'm also like you, rolex doesn't really do much for me and omega to me seems too common... I don't think the have that good a value proposition personally (I can see past the 'brand' inflation) and in all honesty when I see collections with them in I'm like.... oh look another rolex/omega, how original.
Now I'm not saying they're bad watches or anything, in fact I don't actually dislike (think they're overpriced still) the speedy (prefer the bi-compaq though) and explorer 2, and at the end of the day it's a personal choice, but to me I'd rather buy something 'more original' or less common.
Tudor's a bit of a weird one, I like the blackbay and the chrono but at the same time I think they're pushing up into the (before inflation) rolex price ranges where I'm not sure the extra cost for a Tudor over say a decent branded 1-2k watch is worth it.
As to buying watches (actually I do this with most things), it's really simple for me (not in order)....
1) Find a watch I like
2) Do the sums - ie can I afford it, is it really worth the money.
3) Don't put it on credit unless it's an incredible deal, but remember rule 2 lol
4) Do research and look for reviews (I literally have to travel over an hour to a store which might not even have it to look at...)
5) Think when and how often I'd wear it.... no point buying a watch you'll never wear
If they all check out.... buy it lol
I'd also disagree with the youtube comment, yes a fair few do get paid to review positively but there are some who are quite open about 'free watches to review' and the fact they'll be honest. Now some might have ulterior motives to get views etc but you can usually see past them and to be fair I don't really see youtube as any worse than a store salesman pushing the item with a bigger commission.
I really don't understand why seiko is so hugely regarded, every single time I've gone to buy a seiko I've found issues with them (usually on the dial too) and it's a well reported fact they seem to struggle lining up bezels etc.... I'd pick one before a mvmt or something but personally for under £300, I'd pick a citizen over a seiko (I have no issue with quartz), if I wanted an automatic I'd likely go orient (yes I know same group)
