A bargain (IMO) leather deployment strap.
As I took my Seiko Grand Quartz out of my watch box yesterday I noticed the strap was ready to fall to bits at the lug end so I had a look on Amazon for something cheap and saw this complete with deployment for £11.99, ordered Thursday received today (Friday) by lunch.
Quite impressed, real leather, boxed with spring bar tool and four spring bars and instructions, feels pretty good on the wrist, bargain.
