just want to share my experience/findings on three automatic watches that I owned. I understand that automatic watches have a certain degree of +/- in seconds in regards to accuracy. Having said that here are my experience and hopefully someone can shed some lights on some of the behaviors that I found on these watches
First up is my Parnis:
Have the watch for a week, wears it daily for about 8-10 hrs/day with light activities and the watch is loosing about 40-50 seconds a day . Reading other Parnis' owners out here, they seemed to have better luck with these watches in regards to accuracy. So, I decided to take the watch to a watchmaker to get it regulated. He tinker with it and uses a machine that sounded like a cash register and spits out a paper with dotted pattern (I can only see him from behind the counter). Maybe someone here knows what its called
Tried the watch for a week and it is now gaining about 40 secs/day . Brought it back to him, get it regulated again, tried another week and I'm now loosing about 20 secs/day. I think I'm getting close here
Brought it back again to him and told him that I would rather have the watch run a bit faster than going slow - rather go to my meetings/appointments earlier than late. After the third try, the watch is gaining about 20 secs/day. He's nice enough to only charge me once for $20 to regulate the watch the first time. I also tried to position the watch differently every night (first noob experience and for not being patient) and it does not seem to make any difference. One day, I've decided to put the watch in one position for consecutive days (crown down) and noticed that it's stop gaining...after 2 weeks of wearing the watch, it's stop gaining . It's still fast but not getting faster as the first week I was wearing it. After two weeks of wearing the watch, it gains about 2 mins. One weekend, I didn't wear the watch for about 18 hrs (left it crown down) and it slowed down for about 2 mins and 20 secs It basically corrected itself and loosing 20 secs. I notice when I start wearing the watch, it starts gaining again and eventually faster and back to the average of 20 secs/day.
It seems that the watch starts slowing down when it starts loosing "power" - is it true for automatic watch?
Next is my Seiko 5:
I compared it with my Parnis and to my surprise it also gains as fast as the Parnis I thought it may be better just because it's a Seiko and should have a better quality. So, I went on my 2nd experiment with my Seiko. Set the time - can't be too accurate since it does not hack and starts wearing it daily. One thing that I found different with the Seiko, is that when I put it crown down, after use, the accuracy stays, i.e. the variance is so small compare to my Parnis. This position seems to work on my Seiko.
Last but not least is my Orient:
This to my surprise is the most accurate than the other two - regardless the position. It may somehow impact it but the variance is also small regardless what position I put the watch in.
All in all it's been a great experience owning an automatic. I never really involved in my watches before but it's kind of fun getting to know your watch closely
So, share your thoughts and comments and thank you for reading.
