So weird thing happening on my recently purchased San Martin SN004... Seiko nh35 inside I believe. It's held a steady +/- 4 seconds a day for 3 weeks. That's impossible right, it shouldn't be that accurate over extended periods? I need to get it on a timegrapher thingo but every morning I check against my phone and it oscillates between that 4 seconds of bang on. I'm scared to let the spring wind down!
