Rotary Evolution Battery Replacement

[jreclocks]

I have a Rotary Dual face watch ' TZ2  Evolution' with two separate movements, one with subsidiary seconds, the other with a date ring  has stopped working

I suspect the battery in this side has failed and needs a new one but how is the case  opened? Presumably the BackPlate and associated strap must initially be

separated from the case by removing the pin common to the three parts. The case also seems to be of three parts, two bezels and the main mid-section.

There are no "lips" on any edge and then there are the crowns!

Please see the photos attached. I would be grateful if any member who has experience or knowledge of this particular edition  of Rotary's 'reversibles' could

give me guidance 

Thank you

John

You need to examine the sides with a loupe or eyepiece to find where to start inserting a blade tool, like an X-acto type knife. That is safer than a razor blade.

This is round faced watch but I suspect the same method will be required.

But with plastic tweezers, surely.

His technique with metal tweezers is a bit suspect on a battery change hope they were NON conductive.

My bet is that they ARE conductive!  I use Delrin-tipped tweezers for this.

I am an amateur mind you...should you dial down on a hard surface and apply pressure to the hands while pressing in the battery?

Should your fingers be touching the dial?

Surely not. Batteries are replaced withe the mov.t in the case.

Thank you  Clockboy, for steering me to the video of a model similar to the 'TZ2'. I was reluctant to 'jump' right in because

there seemed to be no way of extracting the stem without removing  a bezel.

The other worry was  lifting a bezel, the seams seem so close. I will let you know how I get on. John

The method used is the most likely way to access the batteries. You might be able to pull the stem out with this style of hand remover.To avoid scratches cover the stem first with clear plastic.
