Why my seiko speedtimer 7015 chronograph run smoothly when its day(morning till evening)
But its stop and heavy when its time to changing the day date,whats the problem and how to fix it..
I have been wondering about the chonometer grades of the 2824 and 2892 movements. I understand there are different grades depending on the parts used and the plus or minus tolerances of time accuracy in seconds per day. My question is if one had a sw200 or eta 2824 or 2892 and they were standard grade can a watchmaker upgrade those movements with parts to chonometer? Does anyone offer that service? I am very interested. Thank you
Is the rotor of a 2824 movement compatible with an sw200? I see gold after market rotors on ebay and other sites for 2824 but my watch runs an sw200. Some says sw200 is a clone of 2824 and parts are interchangeable and some state no. Does anyone know definitively regarding the rotor? Thanx
That hairspring looks great, good job!
As for the amplitude (and stopping in 30 seconds?), I suppose you've checked all the usual things, train freedom, endshakes everywhere, peg your holes especially for the fork pivots, check that the barrel has shake on its arbor and the lid is well seated.
