re: OT Watch Thread: How accurate is your automatic?

Anyone watchmaker that says even a chronometer grade ETA is better than a modern Rolex movement is on drugs. It is possible what he was referring to was the particular movement was well within the current Rolex accuracy tolerance. One could certainly argue about the merits of Rolex vs Omega vs GS but basic ETA movements sold by Swatch to 3rd parties aren't in that discussion.

Isochronism could be the cause but to see such a shift in daily rate would require a movement to be constantly in the lower 1/3rd of the mainspring's power, this is very unlikely (unless you are extremely sedentary) especially given how efficient those Seiko movements are at winding. If the mainspring isn't being wound properly then that goes back to a service issue. The band vs bracelet will have no impact.
How much would you expect to pay for service? I ask only because I could replace this watch for $350 if it ever really became a problem.

You can probably find someone that does mainly Seikos to do it for ~200. But the best option, if the situation gets too bad (outside of replacing the whole watch), is just replacing the movement with a new one which can be done for about $75 labor and a new 4r35 would run about $75 and a NH35 under $50 (the NH35 is functionally the same movement).
In general, people run the sub-500 dollar Seikos into the ground and replace the watch. In the past, I have replaced movements but I can do it myself in under an hour but even though a handy person can learn to do it fairly easily the tools required more than offset the cost of paying someone to do the one off movement switch.
My suggestion is as long as it runs, even slow, buy another watch and rotate them every couple of days, if you do this you will never really notice the loss of time over that short of a period.

Brought it in to the local watchmaker. $96 later and it’s cleaned, oiled, and regulated. I’ll let you how it turns out. ??
My dumb arse also bought a SNZH55 on Amazon with rewards points. Pretty cool looking on the nato band.
It comes in Friday so I’m interested to see how it performs out the box compared to the newly regulated SKX.

I'd really like to get into the automatic watch game. I'm planning to get a Hamilton Khaki Field Automatic in 42mm pretty soon. Down the road, I would like to find something from 1954 in military or pilot style to have in remembrance of my dad, who passed away almost 2 yrs ago.

I use the same timegrapher that Obtuse uses and use the Toolwatch app for measuring practical use accuracy. The Hodinkee app is great for syncing time as well.
I have regulated my Seikos that needed it (they are all 0 to +2 s/d) and my two Panerai - again in the same slot. I've never opened any of my Rolexes (16610, 16570, 116710LN, 214270, 114300) or any other of my nicer mechanical watches other than the two Panerai. My 30 year old 16610 clocks in at 0.3 s/d - just back from service at Rolliworks in the Bay Area. All of those Rolexes are in the 0 to +2 slot. I don't have anything gaining more than 7 or 8 s/d. I have a Hamilton Khaki 38 mm hand wind that is -11s/d that I haven't gotten around to cracking the back open yet
I will say that since I got into Seikos, I have been pleased by the accuracy of the ones I own (SKX007, SBDC0063, SBDC0055, SRPC23, SARB035, SRPC41, and an SNZH55 that I dropped an NH35 movement in), and the ease of regulation.
ETA movements (stock and modified) are generally very easy to regulate as are the Seikos.

That is a gorgeous watch
My 8 y o Omega Seamaster is still within COSC standards and has no service yet

I’ll sync my Submariner tomorrow and let you know...

Seiko 4R36A - after adjustment lost 6 seconds from my ipad clock in 7-10 days. Just synced with .gov clock so we'll see. Was way off gaining a few minutes per week when new.
-1.5 seconds in 24hrs

+15 seconds over ~51 hours...so still +7 s/d.

1 sec/day for anything is great, but your seiko is killing it

Not as accurate as my bolt action that I lost in boating accident.

Tissot PR 100 with the powermatic 80 movement. Its a modified ETA 2824 movement that the Swatch group developed. Its a slower beat rate but you get an 80 hour power reserve. It's a COSC certified chronometer so -4 to +6 a day. When I tested it, it was at 5 seconds a day. Great Swiss watch for under $300

They are not regulated at the factory so they can vary widely which is why they have a large accuracy range. Most can be regulated fairly tightly (within 15s/day) but more stable ones are just luck of the draw. They also exhibit pretty high positional errors so how you were it and how it rests at night have a big impact on the daily accuracy.
I give a lot of Seiko SNK80X watches as Christmas presents to people I think might enjoy a mechanical watch. They have the super low-end 7S26 movement and I have had ones that were near +60s/day and ones that would put a dead flat (0s) trace across the Timegrapher with 0.1 or 0.2 beat error. But despite the wildly variable accuracy all the lower end Seiko movements are like the venerable AK47 they just keep going without any maintenance. I know guys that still have them running for over 20 years and the case back has never been touched.

Do you have a hand press? Do you use the same hands or get new ones? Does that depend on the watch?

To answer OP an automatic watch isn't going to keep good time. Not even a certified Chronometer. It's just the nature of the beast. If you are looking for accuracy but a Casio G-Shock.

I have a Stella hand press (Horotec copy) and a Bergeon hand remover. I have always just reused hands. I learned to really respect sub second and chrono hands. Those tiny SOBs can be a bitch to get back on, I screwed up one on a Panerai and had to buy a replacement hand. For me, the hardest part of switching out movements is just getting the movement fixing screws out and back in. The little washer/screw combo can be a real pain.

I haven't tackled this yet. Quite frankly hands frighten me.
