How accurate is your watch?

[Miffy964RS]

Let's see who has the best timekeeper.

Make and model of watch or movement, and time keeping +/- seconds/day.

Quartz owners not allowed to play, of course.


I have a low end ETA 2824-2 +12s/day

[Asterix]

My Sea Dweller is about -4 slow per day.

Not sure about the PML yet - I think it will be around +3 per day

[grumbledoak]

I've never yet had to reset my Spitfire Chrono just for being 'out'. She seems to be within 2-3 seconds per day, but once every couple of months I'll wear my other (quartz) watch for a few days just for a change, so she runs down and has to be reset.

I'm game to try to measure it properly, for a giggle. What would be the 'gold' standard for this one?

[Asterix]

I'd say within +/- 2secs per day would be extremely good for a mechanical watch. Providing it was used and worn.

[grumbledoak]

Thanks, Asterix, +/-2 it is.

I have a holiday coming up, but I'll try a quick test against The Speaking Clock for a couple of days.

I bought a brand new Spitfire Chrono last week. Set it to 'Tim' on Friday afternoon, checked again now and it's gained just 8 seconds in 3+ days. Better than my Daytona

Lucky if it doesn't loose a minute a day!!

It goes through some temperature extremes daily though (Office AC @20, Home AC @24 Ambient @33) and it is due a service sometime a year or 2 ago!!

The 1974 VDO Clock on my dashboard in the car however, never looses a second !

O&W Defender II (Val 7750) gained about 15 seconds over 2 1/2 weeks when I timed it about 6 months ago.

Thats pretty poor! I have a couple (old and new) and they are all very accurate. Maybe a minute or two a month - so 2-4 secs a day?

[dark_helmet]

Try getting the Omega serviced, mine was gaining about 45 sec 1 min per day, now fine after a recent service.

I have a Breitling seawolf avenger that is very accurate, (not noticed a change) but will measure it and report back.

Most accurate I have is my Casio Waveceptor that picks up the radio time signal and sets itself. Very clever and I usually measure my others against it.

Mine is absolutely lousy.

Original Rolex Oyster Perpetual Milgauss. So its what, 50+ years old? One things for sure, it no longer justifies the "Superlative Chronometer" thats on the dial, but I truly don't care - i've yet to see or feel a watch that feels so right on the wrist.

I have to confess, mine are always set slightly fast to ensure I get my train in the morning. The date is invariably wrong as I wear my small selection of watches in rotation. As for timekeeping, I never check. Given my vocation I probably sound like a complete Philistine, but I've always appreciated the design/asthetics/complexity of a watch over timekeeping...Will make an effort to keep to time.

my fortis i', wearing at the moment is +2 seconds per day, i know have the challenge of checking the others

It is but as I say, mine does not live in the best environment, its worn every day all day, in 95% humidity and hot weather, or into heavy AC, bashed about in engines and on boats or pressurized / depressurized in airplanes constantly,

The Tachymetre still seems to be spot on when used as a racing timer and the timepiece itself never professed to being a chronograph.

I also don’t wind it up consistently .... (not that it winds down, but I sometimes it runs for 24 hours sometimes 30 hours sometimes 12 hours before I wind it up again … reserve of 40 hours)

But yea, it is pretty poor, I should drop it in for a service sometime soon!

[lowdrag]

My Navitimer is about 1 sec per day, the Superocean gains about 4 secs a day but the Spitfire Chrono gained to start with but now after six months seems to be just about spot on. I haven't had to alter it or worry for a month now.

[toohuge]

One of my daily wearers is a Citizen automatic with a Japanese movement, anyway, it's a matter of minutes a day.

[speedtwelve]

I have a Fortis Cosmonaut automatic with an ETA 2836-2 movement. It runs +8 secs a day, which has settled from +20 secs/day when I first bought it new.

[markomah]

Interesting thread. I'd never checked before and had just gotten into the habit of re-setting the watch every so often. Inspired by this thread to take a slightly more technical approach,I see my IWC Portuguese has gained 14 seconds over the past 24 hours. Not very good so time for a service, methinks...

Shucks, guess that means I'll have to buy a replacement to wear while it's gone!

[Spooks]

Interesting thread, what would you expect to gain/loose from my humble Breitling colt.
Chronometer or not its intersting to see the how accurate watches are in real world wearing.

[tertius]

Sinn 856, ETA 2893, over seven days daily wear: +/- 0 secs, that's right zero seconds out after seven days.

Checked against my work time-synchronised laptop.
