Tag Timex 21 Series

Launched in 1965, the Timex 21 series covered a wide range of watches. Spanning Marlin, Mercury and Sports models of watches the 21 series is promoted as having:

V-conic movement
Armalloy bearings
Chrome cases
Unbreakable crystals (yeah right)
Stainless steel backs
Chrome expansion bands
Simulated aligator trim

The main difference appearing to be the pairing of specific bands with each watch.
