Eterna 130FTT Plexi size?

CikoNemo · Jan 22, 2026

Hey everyone,

I have been searching online for the right size plexi for the Eterna Kontiki 20 130FTT no luck yet. I was wondering if anyone would know it due to earlier experiences with this watch. And would like to help me out.

Thank you in advance!

Kind Regards.

Presumably you are seeking an original plexiglass and intend fitting it yourself.

The other option is to send the watch to a professional watchmaker and get him to either source an Eterna plexiglass or to fit a generic one.

The last time I needed a plexiglass, I took the latter course and it cost me about £10.

I also had my watchmaker fit a generic crystal to an Eterna Kontiki 20 at the time when he serviced it, and it was a very inexpensive add-on. Having the old crystal in-hand, he was able to measure it accurately.

Unfortunately, I don't have the measurements, but if you're going to replace it anyway, maybe you can remove the old one, measure it, and buy 2 or 3 replacements in closely related sizes.

@Spruce and @Dan S

Thank you for replying! I am not looking for a original plexi those are really hard to find and quite expensive. Just a generic one so i can put it on myself.

Watchmakers in the Netherlands are a bit more expensive.

The plexi that is on the watch at the moment is unfortunately not the right diameter.

again thank you guys for replying so quickly
