Watch Gaskets (2 Pcs) - For Seiko 6139 & 6138 Chronograph Pushers (Water Resistance)

About This Product

Watchmakers and Seiko chronograph enthusiasts, here's a tiny but vital part: a set of TWO pusher gaskets. These are the small rubber seals that go inside the chronograph start/stop and reset buttons (the 'pushers') on Seiko 6139 and 6138 automatic watches. They are crucial for maintaining water resistance. The listing says they fit 'all models' of these movements. The item is brand new but comes 'without tags' – meaning it might not be in retail packaging, just the gaskets themselves. Compatible with Seiko 6105-8110 as well. If you're servicing one of these classic watches, replacing these often-overlooked gaskets is a smart move to keep moisture out. An inexpensive part that protects a valuable timepiece.
