I purchased two straps from Delugs recently for my Yacht-Master 37 and Master Control... ABSOLUTELY PERFECT and by far the best straps for after-market customisation that I have found. Having had a disappointing end to a CUSTOM strap for the Yacht-Master 37 through a different retailer recently, I opted to try a non-custom 18mm one from Delugs that fitted perfectly. Add to that the fact that the straps came as standard with quick release lug bars... They are a 10/10 product in both cases!
This is a stunning strap. The slightly mottled appearance pairs nicely with a number of colors, including various shades of blue and black dials. The leather is soft, supple, and extremely comfortable. There is just enough stitching to add visual interest. And the usual excellent customer support.
Excellent value for the money
