Update..... I suggest anyone looking to buy a TimeBomb off ebay or from a local seller that they consider the $16 investment into a new SEIKO KINETIC WATCH CAPACITOR 3023 5MZ for your timebomb. This is the updated replacement part to get your timebomb running properly. I suggest if you have not done watch work before, that a $20-30 fee from a watch repair guy is your best route. I had mine done at my jeweler and it works perfect. So when making that purchase explain to the seller that even if they cared for it, or its BNIB the cap will not last even if stored away. So figure that in when dropping some cash..... When the watch cap is first installed wear the watch for at lease three days to get a full cycle of charging. That watch should now last at least 10 days off your wrist in keeping time. Whether its BNIB or not, I would just do the upgrade......
