    Seiko spring drive accuracy

    Bought a landmaster spring drive a little while ago and it has been a joy.let me know what you got and how accurate it have been. My Watch is still spot on time after 3weeks,something i find remarkable

    What's the movement in yours?

    My GS with a 9R65 is a very reliable +0.25 seconds per day

    Its a landmaster sbdb015 with 5R66 movement.have been compared to phone and my radiocontrolled watch over these 3 weeks and i am suprised that its still spot on time.its Around 20-25 celsius here.Maybe i was just lucky with crystal,but i think i read somewhere that the best crystals goes into grand series like yours.My watch is a jdm model that i bought new but it was discontinued in 2016 so it have been laying for a while.

    My spring-drive was wonderfully accurate, quite hard to detect any variation week to week. If you want a watch full of mechanically precise engineering but far more accurate, spring drive is brilliant. Very reliable too.
    These are great designs, well done Seiko.

    Welcome to the forum.

    haven't wear mine since years ago...might need to take it out for some exercises.

    I recall the five SD I have, regular 3 hands should be around +/- 3s/per month and the chronograph would be a little bit more..
