Black rust version of Sportmatic 5
This is a continuation of the previously posted Sportsmatic 5 mod.。 The plating on the old watch is peeled off、Some brass is exposed。 This time Sportsmatic 5 also、Under the plating is a metal such as brass、By peeling off the plating, blue rust and green rust occur.、There were issues such as rashes。 Together with installing the screw-down crown、I thought about fundamentally reviewing the case、I tried coating with an oxide film due to black rust。 In the first sportsmatic I made、I made the black lighter and made it a gun metallic color.。 Unlike painting、Hard to peel off and no film thickness、It has a glossy finish。 By coating brass with black rust、Can stabilize the surface、Prevents the occurrence of blue rust, etc.。 I'm about to make Unit 2 with a golden case.。 First of all, a patina that causes black rust(Electrolyte)Soak in。 After a while、In black! It seems that you are looking at magic tricks even though it is a clear liquid。 Take it out of the patina and wipe it、Lightly oil。 Unit 2 is、I tried to make it as black as possible。 It will be a color like this。 Unit 2 is still under construction、1I tried side by side with the unit。 That the、Succeeded in black rust coating。 The chemicals are different depending on the metal、It seems that there are various patinas other than stainless steel.。 The black rust coating is also interesting if the brass case is left with a tattered plating case!
