Marathon general purpose Benrus limited run 505/600 handwind eta 2801. Overall very good condition, but there are a few small dings on edges and the caseback has scratches from being worn daily for a couple years, sapphire crystal is perfect. Tritium is as strong as the day I bought it, pretty accurate for a mechanical, it loses 3-4 seconds a day.<br>$350 covers usps priority shipping and Paypal charge, CONUS only.
