... and the most important thing is you are happy with it.
I find that Tudor is making his homework beautifuly in these last years, offering some new productos based in old designs, which are very tempting and well made.
As a matter of fact, I couldn´t resist buying both a Blackbay and a Heritage (gray dial) myself during 2013.
Now, I can imagine that the decision to let go one of them to make room for another must be a tough one for you, as both are beautiful timepieces with a very nice design, overall finish and attention to detail.
(I specially love the use of classic bevels on their case lugs, something Rolex regrettably left behind in their own models).
Anyway, most important thing as I said before, is you are happy with the exchange made with your friend, and I´m sure he is very happy too.
Regarding straps and bracelets, I prefer to wear my Blackbay with the "vintage" leather straps supplied, and my Heritage chrono with the full black Nato style which came with the Blackbay. I agree with you that the steel bracelet supplied with these watches is outstanding, but I prefer the more casual and sporty look of these watches when worn with a leather or nylon set of straps.
Enjoy your new watch in good health, and thank you for sharing it in your great photography!
Best cordial regards, Abel.
