Thank you, upon further research I found the following link which confirms that my watch is a variation on the Kobold Endurance theme - and my metal bezel has no engraving. In those days Mike Kobold must have been experimenting with a variety of styles.
I still think those early Kobolds, sold online for around $1,000 if my memory is correct, were great watches for that amount of money. The 7750 movements were thoroughly tested, and the cases were made by Sinn. Too bad Mike abandoned that business model and went upscale. I guess there wasn't enough profit or status.
