Eterna Chronograph?

[Harry Smith]

Hi guys I recently acquired an Eterna Swiss wristwatch from a relative as they knew my interest and I can not find any info on it. I believe it is a manual wind day/date and I'm assuming a chronograph due to the markings on the dial. The bezel, hands, markers and crown are yellow metal or plated. It is running but I'm not sure yet of accuracy. Pics say more and the serial number is 3365357:








Can anyone help with some details please? what are the two buttons for and how do they work? How is the date and day adjusted and what is the fourth hand for?

4th hand is date and buttons to set day and month?

[Dave+63]

It’s an annual calendar, the buttons are to adjust the day and the month. The fourth hand is the date display

Looks like a date pointer rather than a chronograph and I presume the buttons set the month and day.

EDIT: Beaten to it

So are the buttons meant to move? they seem seized but I haven't forced anything.

Does anyone know if it is worth anything or just a curiosity item?

That's very useful, thanks guys.

It is indeed a triple date. You can use a toothpick or thick needle to push the buttons.

Nice watch , any watch is worth something 😁
Check out triple date watch ebay to see prices .
Plating looks quite good condition on this one , whats the size ? .
Some are quite small like the Marvin I own with other larger sizes from other manufacturers .

[Harry Smith]

Yes, I've worked out now how to set the complications. I had the back off to have a look at the movement and there are some service dates but I can only make out one date in 1983





The size is 35mm.

Think they start at a couple of hundred quid probably double in good condition and with a service a bit more
