Restoring a classic Seiko 6138 chronograph, like the famous 'Bullhead'? This is a new set of AF (probably meaning hour, minute, and sub-dial) hands for it. Specifically listed for the 6138-0040 Black Bullhead model, but likely fits other 6138 series watches too. The hands are black, matching the original style. Part number reference is BVT00522. They're brand new, but come 'new without tags' – meaning they might not be in Seiko's official tiny packaging, but are unused and unworn. This is a crucial part for a watch repair or restoration if the original hands are damaged, corroded, or lost. Replacing watch hands requires specialized tools (hand levers, setters) and a very steady hand – it's a job for an experienced watchmaker or a very dedicated hobbyist. But having the correct, new hands is the first step to bringing a vintage Seiko back to life. Make sure your movement is compatible before ordering. For the serious watch tinkerer or collector bringing a piece of history back to the wrist. Authentic Seiko style.
