Renata are part of the Swatch Group so I assume would have a vested interest in quality required for watches. I always use Renata and have had no problems with leakage. Leakage problems encountered usually due to low quality batteries or not silver oxide type fitted. Similarly I would expect Seizaiken (Seiko) batteries would be ok. When the charge is exhausted, chemicals become acid and may corrode case and leak. I have never seen any battery manufactured promise in writing a protection for that. I am curious as to when microscopes did start to be used for watchmaking, i remember watching chronoglide 2 years ago when i was just starting to get interested in watch repair. Kalle mentioned that he was one of the first in the Netherlands to use one, so that seems quite recent. I thought they would have been used a long time ago 50s 60s ?, it just seems a logical thing to do. The biggest thing for me is the working distance and the sitting position seems more comfortable than hunched over using a loop. Field of view is also important, being able to see the whole of the movement and some, so you have an idea of where your hands are. Thank you for your effort with the circles! That's extremely helpful and confirms exactly what I observe. Many battery brands are used in the marketplace. We Suggest Renata wherever possible. These tend to be the most expensive but are in our view the best. Renata is a Swiss-made battery manufacturing company owned by Swatch Group (Omega, Longines, Hamilton, Breguet etc). Renata batteries are the most reliable and last the longest too. They are also the battery of choice fitted by premier Swiss watch houses including Tag HEUER, Breitling, Chopard and even Rolex for their quartz collections.

I'm thinking that maybe I damaged the barrel arbor when holding it with a pin vice. That could explain the wobble of the screw and MAYBE a certain off-centered-ness of the ratchet (despite being central in the barrel holes). The point is, I suspect the problem could be solved and yes, I'd be happy to pay twice or three times the price for such a quality battery.

I use nothing but Renata as I've yet to have one leak and ruin a watch. Not that that means anything. It just has not happened to me yet. I have had however, several watches with Energizers and others, that have leaked in the watch. It would be nice if some of you who are in the watch repair field could weigh in on this. Personally, it's totally unacceptable for a watch battery to leak. There are many cheap inferior batteries sold & fitted by both jewellers and ‘repairers’. In recent times there has been a flood of alkaline Button batteries entering the market. Alkaline batteries are entirely useless for watches as their power reserve and performance dips from day 1. For example, if a torch is left on for a number of hours, it will, of course, be considerably dimmer and if left the beam will just fade away. These batteries are unfortunately commonly fitted in watches too. After these cells have spent their energy, they are prone to leakage and will destroy the movement in a watch. Haha it is out but no it doesn't get much use, i only dragged it into the watchroom to make a joke. Its an old 80's 900mm refractor, 90mm mirror ,its theoretical magnification is obviously a joke 😅, i think around 80x is about as clear as it gets, a reasonable view of the rings of Saturn are about its limit. For the last 5 years I've been promising myself a bigger Cassegrain 8 inch maybe. Had a fascination with space since i was 8, seen many things that make me wonder what is really out there.

These of coin batteries and equivalents come in 2 types: Silver Oxide and Alkaline batteries. Silver oxide coin batteries generally last longer and have a greater energy density, so expect to pay a little more for these types of batteries.
