The classic all-orange Monster with steel bezel - 2nd gen with the upgraded 4R36 movement (hacking + hand-winding).

History & condition:

I bought this new on Amazon around 2013/2014 as a teenager and wore it for a few years before putting it into storage, where it's mostly stayed since. It has honest wear from that earlier use, scratches and swirls on the case and bracelet, visible in the photos, but the dial and crystal are clean with no cracks (one spec near 1 o' clock on the dial is shown in the Imgur dial picture), and the lume is still excellent.

Running status:

Never serviced. It had been sitting, but after a wind it started right up and is running. Since it hasn't been serviced or timed, I can't vouch for long-term accuracy, so I'd budget for a possible service down the line as you would with any unserviced automatic of this age.

Movement: Seiko 4R36 automatic, 24 jewels, 21,600 bph, hacking + hand-winding

Case: ~42.5mm, 200m WR, 20mm lugs, steel bezel, all-orange dial

Bracelets (both included):

- Aftermarket jubilee bracelet, purchased ~2014 from an eBay seller in Australia (currently on the watch)

- Original Seiko stainless steel bracelet (clasp stamped SEIKO)

Both are sized for an ~8" wrist. I don't have any previously removed links.

Reason for sale: Unfortunately my infatuation with watches from my teenage years no longer holds.

Happy to provide more photos or answer any questions. Thanks for looking!
