... leather should not be the best option for a diving watch if you intend to wear the watch in water, dive, etc. I wear this watch with its original Oyster bracelet when scuba diving.
But for informal daily wear I love the use of leather straps on my watches, and employ them from time to time for a little change in looks, and find them comfortable and charming looking.
It is very worth trying them! They also give an "unRolex" look to my watch which is something desirable here in my city of Buenos Aires, where robbers pay much attention to Rolex on wrists to try to catch them in certain areas. Rolex is their favorite trophy and the Oyster bracelet is the first thing they seem to notice!
Regarding the watch, you may have the 14060 (without "M") whose two line dial I much prefer its for its cleaner look . Regretably, when I bought my 14060M four liner the previous model was already discontinued.
Have a great day! Very cordially, Abel.
