Yes the 39mm Datograph is iconic and was a game changer but it does not mean it was the best example made in the Datograph line-up 😉👍
In addition, I owned it 3 different times and each time I did not keep it as it did not wear comfortably with or without a deployant buckle. Strangely enough, the Double Split seems to fit better due to more surface area in contact with wrist and not feeling like a hockey puck 🤷♂️
