Story about a SBBN007.
This particular one was ordered from kseiya-san early 2005. I had it for a few months, then sold it to a friend in 2005.
The watch is produced November 2004 serial #0002, and therefore factory battery inserted.
Yesterday I bought this watch back from my friend. He claims he never changed the battery, and I have no reason not to believe him. He tought the watch had a 10year battery. The watch have been heavily used, had all kind of scratches, and still running good. My friend has been working construction. Upon dismantling and cleaning up the watch today, opening the watch, the battery looks original, says Seiko SR43SW. Also if it has been changed it most likely would not be a seiko cell. On the back, watch is stamped for batterychange december 2009 wich never happened. If this is correct, Battery is still running after 8 years and 7 months.
I have now ordered a new sapphire, hammer bracelet and black pvd coated bezel insert from yobokies. Also about to order new gaskets. And I have ordered a new battery. Think one is needed now....
This will be a keeper.
