I agree
It seems that the El Primero needs some "wake up" time after being on the safe for some time.
I don't see this happening with other movements that I own.
I had one that had fabulous precision, after 2-3 days on the wrist but before that it was just inside the COSC specs.
I have a new acquisition that I'm wearing now, waiting for the wake up time, before I start doing any measurement.
I will come back when I perform the measurements.
Cheers
How accurate is your El Primero? . . .
. . . mine has been timed on a machine @ +5 seconds per day . . . . . . and is ~ +2 seconds per day on my wrist with an average of 12 hours on and 12 hours off. The more responses, the better . . . Cordially, Art...
My El Primero is in the same legue
as my Rolexes. During the last month around +3 seconds per day. In general this Zenith is a bit more accurate than my watches in average but can't compete with i.e. my Nautilus, Fifty Fathoms ot Royal Oak. Best, Kari
Would you mind sharing a photo or two, Kari? . . .
. . . I wasn't aware of an EP in your collection! Cordially, Art
No problems!
I bought it as the first "fine" watch after making a bigger business deal. Now the money this deal brought are gone but the watch is still here. It's just the complete calendar with moon phase in yg. So I will take a couple of photos tomorrow and post the...
Here you are!
As requested... This watch has never been one of my pet ones. But now I am going to wear it for a couple of days and let's see... Best, Kari...
Thanks for the macros, Kari . . .
. . . especially the last - check the Masthead view ;-) . . .
Prime Cal. 420 is +2.9 seconds per day ...
Click here for my results from January , the last time I wore it for a prolonged period. My experience generally is that it's very accurate, even better than +2.9 seconds per day. And very consistent too. I went from worrying that it would wear itself out...
An especially good result from . . .
. . . an older model, Andrew - early or mid '90s vintage, correct? Mine is just breaking in, but yours is likely many years removed from its last adjustment, which makes it all the more remarkable.
The Zenith Prime was ...
... produced from 1995 to 1999 and then evolved into the 40mm "HW". So this example is about 15 years old and had a service a couple of years back for a broken sapphire crystal. I should mention that it's not only the day-to-day accuracy, but the long ter...
Does it need to be a true blue piece from Zenith?There are others that uses EP movement
and just checking if you're ok with it Art. Mine is a PAM 72 with EP. cheers PAt
Here's my Class 4 ...
Consistently loses 0.5 seconds a day, one of my most accurate mechanical watches!...
"One of your most accurate"? . . .
. . . I'd say a loss of a second every other day borders on the phenomenal! That there's another in your collection more accurate is astounding. My compliments to your Zenith. Cordially, Art
Thanks for the compliments, Art ...
that Zenith is definitely one of my favorites in my small collection. My silver dial Omega 8500AT seems to lose time in lockstep with the El Primero, losing a second every other day as well.
I had exactly the same model ...
... and it constantly performed at +1 sec/day. However, I found that all my Primeros did not like to rest for a longer time. After being stopped for, say, a week or two, all of them needed one or two days, until they reached their stable rate again. Regar...
