Overview
The legendary Speedmaster has seen many variations over its 60+ year history, but it wasn't until the late 1980s that the first automatic versions were produced. Many of the automatics share a similar visual DNA as their "Professional", manual-winding brethren but with modified dial and case designs. This particular Automatic was introduced in the mid 1990s and is known as the "Triple Date" because of its fairly complicated dial that displays the date, day, and month.

GOOD: Case has many scratches and nicks. Lugs may show signs of moderate polishing with worn edges. Dial and hands may have noticeable stains or marks. Lume may be damaged or show significant discoloration.
Case: The case retains good definition throughout. There are many little dings and scratches that are consistent with normal wear over 25+ years. The case back engravings and hippocampus are clear, sharp, and deep. The tachymeter bezel shows wear, but all numbers are still clearly visible.
Dial, Hands, & Crystal: The dial is in very good condition and the tritium has aged to a nice golden hue. The hands have aged to a more greenish tone. Both have a similar UV response under black light. The crystal itself does not have any scratches, but there are a couple light streak marks to the outer AR coating that can happen to crystals with this feature.
Bracelet/Strap: The Omega 1560 bracelet shows wear as well in the form of many little hairlines, but there is no stretching.
