Hello. I saw what looks like the military arrow on the case back of a West end Secundus watch. Does anyone know what the engravings mean? Thank you.

 

From memory Indian Army marking.

 

Interesting. I thought most have CSI ?

 

If I remember correctly the latest thinking is that CSI is Canteen Services India as opposed to Civil Service India, a bit like a NAAFI. I don't think that is 100% definitive at this point though. The Z number is interesting.

 

There is also an A inside. Not sure if that adds to anything ?
