There is no good modern Daytona on the market. Once you hold a genuine Daytona on your hand, you can spot the flaws on the rep quite easily. I would suggest you look into BK/ WM9 on the secondary market. They are quite accurate.
Your boss and your friends are into watch.. but that doesnt mean you can't also build a datejust, date, 5500 ariking frankens.. with geninue parts...to me, people with vintage watches have better taste
