I`ve always wanted one of these but they are rarely seen . I bought this from a watchman just up the road from me.
Winding Indicators were commonly used in navigation chronometers -- you wouldn`t want your clock to rundown mid Atlantic !
They appeared in railroad grade watches around 1900 & were never made in large numbers due to the extra cost of gearing @ $5 - $10 which would add a large % to the initial cost.
In 1913 Waltham`s 18s & 16s Vanguard indicators were both the same price @ $61.
My watch , made around 1907 has a ratchet/slip mechanism which keeps the pointer between the scale limits ie. UP & D/N

Very Nice Derek, I need to find one myself.

Nice! On my list for sure.

The Waltham movement no. 16168350 , one of a batch of 800.

Nice watch Derek, the only thing better than an 18s Vanguard is a wind indicator Vanguard, they are some of the finest 18 sizes ever built, bar none!!

Sweet, I have a Waltham 23j as well. I have mainly BW Raymonds (19,21,23J). Love the wind indicators.

Mine must be broke. I held the up high in the wind and the hand never moved to show velocity

Thanks Rick, I know a young man who bought one of those big plastic green wrist watches, looked liked a Sherman tank wheel. This watch did everything, gave you the time around the world, ambient temperature, surface temperature of the sun & altitude etc.
We were stood on the beach watching the sea one day when I ask him , " Whats the altitude here ?"
" Its 800ft."
"I think it might want recalibrating, or throwing in the sea "
