Maybe you dont notice it but all 4 have 26/24 strap , i dont know why but 2mm makes a lot of difference for me , the look changes totally with that. Long time ago when i bought my first fiddy i try it with the common 26/26 convination and really dont like me in fact i left watch in my watchbox for a long time , some day i was trying straps in a radiomir i use the one in the fiddy and i interchange it. And wow fiddy with 26/22 converts in a super confortable ans classy look watch then i test it 26/24 in 217 and since that day this watch its my all time favorite
