Going with my modified SEIKO "Baby Tuna" in multi-toned blues; it originally came with a blue rubber strap and bezel shroud, as well as a basic mineral crystal. The rubber strap was switched out in favor of a nice, thick leather strap with heavy blue stitching to match the watch's basic color scheme, and the rubber bezel shroud was replaced with an aftermarket steel version. Finally, the mineral crystal was replaced with a thicker, domed sapphire crystal. The results were, IMHO, amazing...
