Hi, I have a lovely genuine ostrich strap on my vintage Seiko dress watch. I want a deployant which is not bulky when on the wrist and which is also comfortable. I like the look of the single clasp for IWC and a double for Maurice Lacroix. Both are around £25.00 on ebay and are just replacements not OEM at that price. I have small wrists about 7 inches. I would welcome opinions as to which type is thinner and which is generally more comfortable. thanks jack.
