I was visiting the London boutique on Saturday to have a second look at the white gold Portugieser Perpetual Calendar (IW503301) and noticed that what I originally thought was the same strap as on my Portugieser Auto (IW500705) is in fact a nicer, more textured Santoni version (with the orange lining).
I asked about cost; the standard one is £250 the Santoni one is £320. I'm happy to spend the extra for what looks like a better strap and I assume lug width and deployment dimensions are all the same.
I was wondering if anyone had thought about, or actually gone ahead and fitted the Santoni alligator strap to a more standard Portugieser?
