If I remember correctly, I think I haven't seen any of the quartz movement made by Seiko/Citizen uses lithium battery (CR2012, 2016, 2025, etc) but there are many in Casio's lineups. I wonder what's the reason considering that lithium usually has more capacity and longer shelf life AFAIK. Honestly my knowledge about Citizen is almost nil considering that there's not much talk about their movements.
LOL now that I almost post this thread, I think I know what the reason is. Considering that Seiko/Citizen usually makes analog movements, lithium may make their movements unnecessarily thick (unlike digital). What do you think?
I looked up Ronda database and their 715Li quartz movement thickness is quite acceptable at 4.6mm.
