Hi guys
!st timer here and mostly ignorant.
have an Newmark mk11, 13 lignes. pin pallet oldie(worn) Original balance replaced with closest match but watch losing 50-60 minutes per full day.
Reckon the balance is too heavy, Is that ok ? And so plan to skim balance rim approx. 4per cent of total weght to speed up.
Is this viable ? Would decreasing weight of balance speed up timekeeping to proper levels ?
Amplitude seems good, healthy tick and runs for 27-28 hours on full wind,cleaned and oiled.
