I have the PO with 8800 movement and use Watch Tracker

I timed it from Nov-March and it was +18.0 total or +0.2 spd
Recently I started timing on Aug 22 and today it is at -0.8 total

 

PO 8800; running about 1s/week, so I selected ~4s/month.

truly incredible

 

My smp diver varies from season to season- it can get quite consistently hot where I live. Some months it hardly gains or loses anything when averaged out over the month and other months it can be 25 secs fast. Once it took 5 months to gain one minute.It uses the awesome 8800 movement.

 

I find the poll metric a bit odd, as the majority on here would measure seconds per day (spd).

I selected 21-30 per month, as mine runs at +0.8 spd.

In any case, I've found the 8800 movement to be incredibly stable, having not deviated much from this rate since buying it around two years ago.

 

Apparently most WUSers don’t really care that much about watch accuracy or precision. I started a thread recently on how so many sellers here don’t provide info on their watches time keeping and most people responded “so what? It first matter.” Weird.

I care.... to a point. When I got my AT I checked it 3-4 times over the first week or so, and now just check it about once a month, as long as it's within spec then all is well.

 

Mine with the 8800 movement is about +7-9 spd when off the wrist and +1spd when wearing.

 

My Railmaster runs about +2 to +3 seconds fast consistently, well within spec, and well within my happy place. !!!

 

My Railmaster is about +4spd fast.

 

No idea per month. I've checked them once or twice over a day just for fun. Seems fine. 1 or 2 seconds on both them, so maybe 30-60 per month?

 

I never keep a watch running for a month save for my PC which thankfully has no second hand!

 

In reality and this is based on 4 Omega master chronometers I have, they are usually within 2 seconds a day with very little positional variation. On the wrist they tend to be almost dead accurate for weeks.
