So my master control calendar arrived today - absolutely as described by xupes.

It’s on a leather strap that fits onto a concealed deployment clasp.
Problem is the strap is only just big enough for my wrist and I want to put a longer leather strap on it - so the strap looks better when on the wrist.

I’m not previous about the strap being JLC branded but I do want to utilise the JLC buckle.

The strap is 22mn at the head tapering to 18mm at the buckle end and I’m having real difficulties finding a strap ? Needles to say shelling out £300 for a JLC branded strap is something I’d like to avoid.

Any advice / pointers appreciated.

Thanks
Simon
