My Citizen E820 movement based perpetual calendar chronograph only gained about 0.0167 seconds a day for the past year.  6+ seconds a year still sounds like a lot, but that's what many mechanical watches can gain in one or two days.

Drats lost my post. How did you measure it so precisely? I just eyeball it and my 9F62 is still right on after a year or so. I think the temperature compensation and magnetic protection helps a lot to get that accurate.

Curious if it was (mathematical) division or something like Twixt for iOS... I discovered Twixt when I had the exact same idea when reading HPA post about EXIF data. They also use the microphone (Kello for iOS), which might work well, who knows.

It's man jewelry. There isn't a single thing I do in my life that a matter of seconds relative to someone else makes a difference. I'm an engineer and just flat out appreciate the art of watchmaking. And that I get to wear nearly all of my watches for free or profit, if you buy right.

That said, this is a cool app.

As an engineer why not appreciate the art of accurate watchmaking? Surely one could be entitled to do so if they wished, whether they were an engineer by trade or not, notwithstanding their bargain-hunting skills.

My point is I don't care. Not that you shouldn't either.

I happily own a GS with 9F movement and a solar atomic Casio, due to their accomplishments as well.

I measure it by eyeball, if I care (I only care if inaccuracy is enough for me to really notice).  My watchmakers use very expensive measuring tools.  I'm not sure what HeadphoneAddict uses.

 

I set the Citizen to atomic time and then checked it approximately one year later, then divided the 6 seconds gained by 365 days in the year.

 

But I also use an App called WatchTracker on my iPhone that lets me see how the watch compares to atomic time and set it, and then I can mark data points along the way over hours or days or weeks, and it will show me if I am pulling away from Atomic Time or falling back.  Obviously the more data points and the longer the test, the more accurate. 

 

For example, I ran a test for about 15 days on my Victorinox Dive Master 500 recently (with ETA 2892.A2), and came up with an average of +3.5 seconds a day after over two weeks and 16 data points.  But it could see that runs faster when I'm wearing and active, and slower when I'm asleep.  So, it might gain as little as +0.5 sec a day, and other times as fast as +6 sec a day, but it averages out over time.

On the other hand, my Planet Ocean 2500c runs 4.7 sec a day fast no matter if I'm active, asleep, on the winder, etc.  It has almost no variance since I had it serviced in July.  I can have it adjusted to be as close as +1 if I want, but if it aint broke don't fix it, and it's within COSC specs right now.

40mm is definitely my limit.

Got sick of being the only person on HC not buying watches lately.

 

Went out looking for a Blancpain Fifty Fathoms or a Tudor Black Bay Blue but found neither.  Ended up with another Superocean.  Got the mesh and the gator with deployant clasps.

 

 

Jeff - the Tudor Pelagos is awesome, wish it fit me.

You need to venture back up to NYC for the good stuff.

Yeah I know.  I went to a recommended place here locally and they had nothing but Rolex.  Evidently there is a place at the high end mall that I can find Blancpain and Panerai.

 

Can't find any of my watch tools anywhere to size this giant mesh or put on the crocodile deployant.

 

I did however find some Panerai and Bell & Ross accessories to take out to Al in June though.

Looks nice on you.  The new 42 might look huge, but you never know.

 

So, you posted at 5:31AM and your 24 hour hand shows that time, but your 12 hour hand shows 7:31AM. So I'll curious to where you have the two time zones actually set?

That looks great on the mesh.

24hr hasn't been set yet

And found a fringe benefit of 24hr, you know when your on AM/PM

Come to Sydney Jeff, lots of options here

I offer watch burn-in services.

The watch place in pentagon city has some pretty nice stuff in a small footprint. Of course Jeff may giggle at it

Mesh is much nicer than I had expected. Very comfortable.

Mesh is great. The only bracelet I've had that's as comfortable and looks great is the one on my Raymond Weil Don Giovanni.

Jeff, I suggest Chrono24 and WatchRecon for target acquisition purposes. Stick to the top-tier sellers and you're very, very unlikely to get a fake or an empty box.

eBay from people with 0 feedback or at most 50% approval is my preferred method of finding quality stuff.

Croc strap is pretty great as well. Don't know why I do not have more deployant bands.

I'm wondering why I haven't considered Breitling before.  I'm usually fixated on Rolex and Omega (with Victorinox and Luminox as my beater watches).  Maybe the askmen.com watch snob ruined them for me?

 

I've been thinking about a Jaeger LeCoultre Master Compressor Diver or a 36,000 VPH chronograph (Striking 10th maybe), but my budget wont support that right now.  I'm not into fancy watches like PP or VC.

Scrolling up towards Jeff's pic yielded a very different view suggesting leather attire of a different type and location.  

 

What's the Head-Case Safe Word, again?

Went to a nice shop over at the mall and the Omega Boutique tonight.   Lots of things I need to buy, including a pair of Dark Side and Gray Side of the Moon Speedmasters.
