I found this a very satisfactory solution.
Items used.
A cheap watch (I paid the equivalent of about 5 US dollars).
A key ring with fob/logo.
A small section of double sided adhesive tape.
Obvious but I'll go through the making of it anyway!
Remove the key rings fob. I used a small hacksaw to cut a section then twisted the remains away with a pair of pliers.
This leaves a leather key ring with a small horizontal leather tubed 'flap'. Take the watch and remove the spring bar pins and strap. Retain at least one spring bar pin!!
Refit the watch to the key ring with spring bar pin through the flap. Add the double sided tape to the underside to retain the watch and prevent it:- a) flapping around and b) putting a strain on the single spring bar retaining pin.
Result is an easy-to-read clock while on the move!!! AND
