pvd coating information a member from this board had a lot of questions about my new PVD PAM111. so i thought i give my answers in this thread, for more information about PVD-Coating. i'm not a dealer, i'm a private person and this kind of work with pams is my passion. my friend, a really good watchmaker-master, i've got from him a lot of experiences. so i wanted to start a pvd project with a pam111. i was searching for a pvd-coating company. the most companies makes pvd-coatings for metallize of tools. some makes that for industry-products. like doorhandles, car-parts, reflectors, halogen-reflectors, etc. you have to know pvd is not black. pvd is a kind of synthetic-material and transparent. this transparent-material gets with add-on of color-material the different pvd-coatings-color. black, dark-black, silver, gold, red, blue, etc. is the object polished -- after pvd-coating the surface is polished. is the object brushed -- after pvd-coating the surface is brushed. the pam111 got for the surface the bead-blasting. so, the bead-blusting ( regular is glass-ceramic bead ) is one of the surface-work. jewellery and glasses-frames with black pvd-coating that makes special companies. most in swisserland. i had luck. in my location there is one company, they make pvd-coating with different bead-blasting structures for jewellery and glasses-frames. one person checked for me the mix of the glass-ceramic-bead with a share of corundum. the mix is 70-75% glass-ceramic-bead and 25-30% corundum. thats why the surface of the watch looks like the gen pam. the procedure of pvd-coating is in a high-vacuum machine with 60-300 degrees temperature with a ionic-process. so, each gasket would burn. important is that the watch-case are in separates. first take out the front-glass with gasket. then the bezel. between the bezel and the case is a teflon-gasket, in the crown is a gasket-o-ring and in the case-tube is a gesket-o-ring, and in the case is a gesket for the case-back. crown without stem ( the stem is screwed in the crown ). the crown-guard has a link for the lever, and in this link is a plastic tube with a pin. important: no bead-blasting in the screw-jack holes and bezel-case-edge and case inside. ( caseback without pvd-coating ). why no bead-blasting: otherwise no waterresistent. maybe i could help for a better pvd understanding. rolli ps: from palp comes the new thicker crown. some pictures Pam111 PVD with K.Wong gen Croc:

PVD Pam111: i thought why not a pam111 with pvd coating and super luminova C3. so i began the project. first i needed a pam111, this was easy. money and a good dealer. a good watchsmith -- i know. 1.) divide the case into individual parts. 2.) for pvd coating -- case without frontglass and case back bezel, crown, crown-guard with lever, screw-spindles, litlle screws. 3.) a company for pvd coating -- near 30 km from my location. 75% glass-ceramic and 25% corundum -- bead-blasting. presentation for the surface -- different pictures and various pvd-exemplar. the glass-ceramic-corundum mix makes the surface structure. then in a special vacuum machine the pvd coating. all case parts in one run. return pvd case to the watchsmith. intermediate came the super luminova C3 from the company RC Tritec / swisserland. divide of the sandwich dial, and lay on with super luminova, the same with the hands. be careful you need a perfect super luminova mixture for a better luminous power. super luminova have to dry for round about 5-6 hours. in a special stove with 60 degrees ca. 1 hour. ok, reassemble of the case parts, frontglass with gasket, crown with stem and new gasket-o-ring, crown-guard and lever, movement adjust and reassemble with the sandwich dial and hands. reassemble with the case, case back screw down, completed. a little bit later i get a new thicker pvd crown from palp. so this is my pam111 pvd. here some pics: enjoy yourself rolli PAM111 PVD with Strapmasters Croc Khaki:
