Simple rubber strap recommendations for 556

[NewWatchTime]

I'm looking for a simple natural rubber, high quality strap for my 556. Probably constant width 20x20. Something along the style of these Bonetto Cinturini straps:

Model 270:


Model 320 (too thin? yes, only 2mm):


Model 306 (too thick? maybe, but it tapers right away to 18mm):


Any first hand experience with the above? Thoughts? Other recommendations? Photos of the rubber you are using on your 556?

If I must choice one of them, I will select Model 306.
Because 566 is quite thin watch, so it is good combo with thick band IMO.

Doing some further research, it looks like I can cross off the list the following:

Model 320 - it's only 2mm thick according to the specs here

Model 306 - it tapers to 18mm right from the lugs, I'm looking for something that's straight 20mm to the buckle.

Not too wild about the 270 either with only 1 keeper and DIY holes.

So... I'd love to see some nice suggestions.

I'll add Model 300 to my list too, though I'm not sure how I feel about clasp vs buckle on rubber.

No 556 out there on rubber?

How about a Hirsch Pure? I think it tapers but it is a very nice strap.

I like the Hirsch Hevea too, but they taper.

Turns out even the BC Model 300 above tapers. Not sure why it's so difficult to find a quality leather or rubber strap that's straight 20x20.

I just ordered a Sinn rubber strap for my 556A. Gimme a few days and I'll post pics of it.

Excellent. Which one did you get? with the small or big clasp? I'm very curious whether the strap curve fits the 556 lugs well as the note on the watchbuys.com site has me worried: "Keep in mind that using this strap on a smaller diameter watch (less than 40 mm) or on a small wrist diameter may not be a good fit for this strap."

I'm surprised that Sinn uses silicone straps rather than natural rubber given the price of their straps.

This is the one I have gone for:

Neil at Chronomaster reckons that it is really good quality and "not like the plastic straps on a Casio." I'll certainly get some pics up ASAP. May arrive tomorrow so fingers crossed. Unfortunately I can never seem to get into the watchbuys website from here in UK.
