After months of enjoying the forums here I thought it was finally time to join. My first post: I won't bore you all with too many details about myself - other than to say that my enthusiasm for watches has grown faster than my wallet - I own a Rolex Oyster Perpetual Submariner and an Omega Seamaster Planet Ocean - both secondhand but in perfect condition.
Anyway - to the point of my post which has been bothering me for some time:
Does anybody know if the size of a mechanical watch movement affects the precision, reserve power etc? If not, then why are multiple sizes available from the likes of ETA? Why not simply make one smaller ligne movement - and then fit it into an over-sized case?
Any ideas or thoughts appreciated.
