Hi All I don't think that the rubber strap for my Seiko 7a28 Yacht Timer is long for this world! Ideally, I want to keep the watch as original as possible, so I'm in the process of tracking down a replacement. On the back it's marked as GL21A 20- I think the part No. is 984G421A. If anyone has one or can enable one that would be greatly appreciated. Many thanks for your help Nathan
