Hi, 5726 and 5711 don't have the same size, so I doubt they have the same strap size. Maybe a 5711R strap would fit on a 5711/1A? I'd like to know too. I don't think Patek Philippe would easily help do that. Cheers Dje
I completely forgot about this model; a perfect match to 5711/1A! Will check it out this weekend. Thanks Dje! And have you gotten a 5711? You were seriously considering for it a while back. Saw in your posting
