A decent clock should be standard kit on a Mog, more use than a rev counter, all that's good for is calculating the speedo inaccuracy
I completely agree, first for the hour displayed (isn't it it's purpose ?

) and second for the look it offers, the dashboard is IMO nicer with a clock

What I do like is that there is no wiring so no way for making the battery goes down so you can drive when you want without thinking about the power of the battery
BTW can it be opened without descrewing it ???
Anyway your dashboard is very nice like this
