Patek Philippe

i really like the 5712/1a but am less taken with the bracelet. I was wondering if anyone has tried fitting the leather strap or the composite one on this watch instead.?

When I looked at the 5712/1a I could not see an easy easy way to remove the bracelet. The final links/hinges going into the case do not appear to have screws to disassemble them. In the 5712G and R both have end links that can be removed and in theory you... 

my plan B was to look at the 5712g if it wasn't possible with the steel version. I'll have a closer look at the areas you pointed out. many thanks

That is a good news as most luxury sport watch come with a rubber strap. I would love to see a picture of 5712G or R with a composite strap.
