IJN chronograph

[rabbit indy]

Hi

I bought this chronograph(stopwatch) recently.
夜行秒時計三型
It means "night second clock type 3" ?
I have ever seen type1 and type2, but I don't know this type 3.
I want to know more information about this watch.

Nice piece!
Sorry cant help you with the Kanji, but is there anything inside the back cover, or covers? It looks like an old English pocket watch i had, there were two covers on the back. A finger nail is all you need to pry them back.
Maybe some extra pictures on an angle or the sides??

Hi STEGEL


I got a tool to open my watch.
So I can open it (only one cover).
There is 6 digit number inside cover, 133866.

The word in circle on the back means "boat/ship"

I think these watches were part of the aviation practice camera that was shaped like a machine gun

"夜行" means night time or night light (you copied the 2nd word differently from your watch)
"秒時計" means "seconds" gauge
"三型" means "type 3"

I am puzzled, why night? Does it illuminate in the dark?

Hi Ludwig-K

I can open second cover. There is no marking. 5 jewel?
You are correct watch has no fluorescent paint on clock face.
Also I don't know.

夜光秒時計　三型

I write 夜行、i's mistake.
Yes "航" means ship or boat, this watch was used by sailor.
