My Omega Seamaster gains ~2-3 minutes a month (so roughly 4-6 seconds a day.), it's rather annoying but I understand that it's pretty common for an automatic mechanical watch.
- Badfood 5y agoFor something mechanical operating under random g forces and over a wide temperature range, that accuracy is truly astonishing.
- kenneth 5y agoFully agree, automatic mechanical watch movements are truly a marvel of engineering. The fact that the movement is powered purely by the kinetic forces naturally applied from wearing it, and can reasonably accurately keep time over years, under a wide range of conditions… is truly impressive.
- TheManInThePub 5y ago> My Omega Seamaster gains ~2-3 minutes a month (so roughly 4-6 seconds a day.) That falls within the bounds of accuracy required of a Swiss certified mechanical chronometer (that is to say, a clock accurate enough for marine celestial navigation) and is pretty good. As a marine engineer I have a genuine and real appreciation of mechanical chronometers, though any working watch/clock I use will always be quartz as for accuracy and price, nothing else comes close. https://en.wikipedia.org/wiki/Marine_chronometer https://en.wikipedia.org/wiki/Marine_chronometer
