Here's an Ollech & Wajs classic Selectron Computer manual, in steel and chrome.
Check out that complex, jet black dial - doubling as a slide rule - ... and the red date.
This one, under the Selectron banner, was used by aviators in the Vietnam war.
Classic larger dimensions: 38mm wide, excluding the unsigned crown, by 44mm from lug to lug.
This watch wasn't kept in a safe. It has seen some action. The crown and the surface around the case back show some wear-through of the chrome plating; there are scratches and dings throughout including some deeper ones on the stainless steel case back.
The unidirectional bezel turns easily. it is in good condition, with some wear, nothing major.
The 17-jewel manual Ebauches Bettlach 17-jewel movement keeps excellent time. One note: the crown has a slight hitch as it pulls out to set the time. Nothing to affect the operation or time-keeping, but worth mentioning.
The aftermarket steel bracelet will fit a 7.5 inch wrist.
