I like this watch! But I would like to own it as long as my other TG watches. (wearing a 999.206A from 1990 right now) After request to the TG customer service I received twice the information that it is not possible to replace a worn battery, even not from the TH service. Answer was, that I can charge it at least 500 times before it drops capacity. In daily use, after two years you are on 700+ charges and out of warrenty = out of the change-to-other-model-program = this watch is very close to a disposal item. I still look it up on the aftermarket frequently, but I guest it will never be a smart buy. Having two interchangeable batteries in a stainless steel cover in TH quality to hook it up on the back (having no.1 in charger & no.2 on watch v.v.) would have been a brilliant idea und having me in the boat. Still leading to the problem, that there probably will be no phone to connect it to in ~10 years, but still a nice piece of art and able to tell the time. I actually don´t understand the connected´s policy. Offer battery replacement and you can call me in.
