At the moment, itll consistently run or about three seconds when you give it a hearty shake; sometimes, though, you can get about 10 seconds out of it. The minute counter does turn over and all chrono hands reset to zero, albeit a bit listlessly. The day and date quickset properly and turn over at midnight, but the day wheel is a little sticky and tends to hang partway. The start-stop pusher is fairly crisp; the reset pusher definitely has some excessive resistance and feels gummy. The watch appears all-original and has all its hands. The dial is in fair shape; there is a decent scratch just east of the Speed-Timer text and the subregisters are fairly stained. The crystal will need to be replaced as its chipped and pitted; its also not staying in the case although I couldnt say exactly why. This seems to happen to bullheads with surprising frequency, for whatever reason. The case is in fair condition as well. There are minimal tool marks on the caseback and quite a few little dings; more importantly, the case looks to me as if it might have been polished. The machining on bullheads can be subtle, but this one looks more subtle than usual to my eye, and some of the dents look oddly rounded-out. I truly go back and forth on this, but prefer to err on the side of full disclosure. Take a look at the photos and judge for yourself. Under the hood, theres quite a bit of gunk and considerable wear. The winding weight is rather pitted and there appears to be a minuscule amount of rust, mostly on some of the screws. I have not had the movement out of the case to inspect it further. Ive described the watch to the best of my ability and tried to disclose any issues, and I will happily answer any questions and send further photos on request. Please assume that it will need at least a full servicing to run perfectly. The item “Seiko 6138-0040 Bullhead for Parts or Repair, March 1976″ is in sale since Saturday, April 25, 2020.

This is a later example (no 70M or Resist text on the dial, Resist horseshoe caseback). With the caseback off, the winding weight is quite corroded and theres a touch of rust to the visible portions of the movement, which I did not remove from the case (theres mild rust to the movement ring, too, and I dont want to dislodge bits of it and then have the watch start running in transit). The pushers give a satisfying and appropriate-feeling clunk but the minute counter, at least, does not reset. I tested the watch with a borrowed stem, and the day and date do turn over (but the stem was also incorrectdont even askand not long enough to test the quickset). This watch has been victim to a fair amount of meddling. The hands do not appear original to me (although they certainly dont look new, and were likely lifted from another watch of similar age), with the exception of the sweepwhich does look original but is floating loose in the case. Also loose in the case is the SEIKO nameplate that ought to sit near the top of the dial. The crown and stem are missing, too. Cosmetically, the watch is in decent shape. There are some significant scratches to the 5 oclock corner of the case, but the tachymeter bezel is in really nice condition. You can see in the photos that theres some gunk around the 100 mark; this actually scraped off with a fingernail after I took the pictures. There are tool marks on the caseback. Ive described the watch to the best of my ability and tried to disclose any issues, and I will happily answer any questions and send further photos on request.
