It's the newer version mbw or mbk I think as it's known that's come s from reg on the other rwg, mapman57 installed a flat t-19 stern crystal and a gen insert for me, softened and aged the bracelet a bit, lug holes have been redone and a gen set of springbars added, 580 wso end links also, feels and looks great in person
Go the other way and have lug holes with the 93153,I've got the same on a mbw serti,plus my gen 16613 has the same set up if you need any pics,are you a member on rwi,theres a great thread on the 16613 builds inc pics
There's a gen 93153 on rolex forum with Ss clasp and 401b end links for 700 pound, not sold and been there a few weeks, good condition, there's also a gen dial/insert for sale also
