Strange they didn’t ring your markers in white gold like they the Explorer II...but I guess they had to do something to set the dials apart.

I don't think they started doing that until they got into the 166XX series. But i could be wrong.

I wanted this one specifically because it's from the year i was born.

Right around that same time though (?), because they went to black marker rings after the first 4-5 year run of the Explorer II.

Gorgeous.
I LOVE vintage Subs.
I keep dreaming of this one...I will have it someday:

Just did the 24hr challenge. My Tissot 1853 lost 3 seconds in the 24hrs.

This is stuff my dad worried about in the 90's.

Just looked and seems like it's the 168000 that first got them for the sub family. That would have been a couple years newer than mine.

I use a Timegrapher Weishi 6000 to determine the rate of my watches.

The spread of my watches is from -2 to + 11 seconds per day.

The very best are 2 of my Pateks, 3 Rolex and 4 Omegas that all have rates under +1 second a day. The worst are a vintage Omega Seamster 300 that runs +12 sec/day and an oddball Panerai that I have never been able to regulate better than 15 sec/day but the movement has an unusually low amplitude that seemingly can't be corrected.

85% of my mechanical movements are better than -1/+3 seconds a day but it helps that I regulate them myself.

In the end from a practical POV since I usually only wear a specific watch for a day at a time even a watch running a minute a day slow or fast would make little difference. I monitor the rate (but more interested in the beat error and amplitude) mainly to keep up with the health of the movements.

If one wants an extremely accurate mechanical movement the best options are new(er) Rolex, Omega, Patek and Grand Seiko movements.

This is probably a good place for me to ask this question.

My seiko samurai 4r35 was at +6 seconds a day and stayed like that for 5 or 6 months. Then I checked one day and it has started running slow around -8 seconds a day.

Any reason why it would shift?

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.

That’s exceptionally good for a Seiko 5. A real keeper. I’ve had a couple of those which would be off by as much as ten minutes over a month.

In general, a shift like that means it is time for a service.

There can be a number of reasons why you started running slower almost immediately but a hard knock is high on the list.

Lower end Seiko movements also known for high positional error. Did you take the watch off at night? If so dod you change the position it sits in while off your arm? Did your daily routine change significantly?

With any watch that gains or loses any significant amount of time per day you can experiment with taking the watch off at night and leaving it in different positions on the side table. You will likely find a position that helps offset the gains/losses during the day. It is especially helpful with the lower end Seiko movements that show significant differences in rate based on position.

In short a big change to a slower rate usually means time for service if nothing about your wear pattern changes, a significant increase in rate is sometimes caused by magnetizing the hairspring which can be fixed at home for cheap and can be verified if you have a (old school) compass.

Thanks for the info. I’ll mess around with how I set down at night.

Along with everything Obtuse said, know that watches (short of some kind of constant force complication) will run faster or slower depending on how tightly wound the mainspring is. Is it possible that you are letting it get a bit more run down these days than you were previously?

My steinhart ocean one has been an absolute beast. When I had it cleaned, the dude at the repair shop said it has better movement than a Rolex. Hell if I know but I beat the shite out of it and it keeps working. Best $500 watch you can buy.
My Elantra is better than your Porsche 911 because the guy who works at the Car Wash told me.

Additionally, not all Rolexes are created equal.

I suppose it’s possible. Do you think switching between the bracelet and natos would alter it?

I have three autos

Don’t care about their precision.....I always have to adjust as my winder broke and I don’t care.

Rolex sub and Marathon JSAR are my main watches. Third is a dresser Hamilton.

I will say there is something satisfying about adjusting every few days.

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.
