Thanks for the reminding me.....

Fine. Let's discuss about accuracy.

Here's my summary and feel free to correct me if I'm wrong.

Open these in two browser windows and compare:
NIST UTC Time
Malaysian Standard Time

Depending on the user's internet connection ping times there is no difference in the time displayed. I can't see the fuss over which standard should I use. Someone has too much time trolling around.
Posting about stick up the ass, and asking whether my phone is Quartz COSC specs does not help giving a proper reply either.

All hand phones that I have used have an internal clock that can run with or without the auto update enabled. All will run just fine even without a sim card and the accuracy will depend on the internal clock. Does it have anything to do with Maxis? Anyway I'll continue the test and check till the end of this month and see if h/p can deviate 10s, 20s or even 30 off the time standard.

So far I've seen it deviate 5 +/- 1s from the beginning of this month. Feel free to observe yours too, and if it doesn't then make your own conclusion.

Observed accuracy for the past 2 days is +6 of the standard time.
(86400+6)/86400 =100.007%

Good enough for daily use.

Been using the same h/p for the past 6 years and haven't worn a watch for the past ten years till May. My renewed interest in analog watches is that it is easier to visualize time and time elapsed.

There are many people out there that do not use a wristwatch and my intention for posting the comparative test is not to show how accurate the watch is, but it is to show how it can complement the h/p. All one needs is a quick glance, even when there is a variance of 30 seconds +/- or more, one can still tell time fairly accurately to the minute using a cheap Seiko 5. I no longer keep taking the phone out of my pocket to check the time now. Perhaps my previous post and lack of information is not ideal and gives the wrong impression to certain people.

Finally, if I no longer have to respond to a Mr. Obvious or a Mr. Troll then I have nothing to complain either.

2006 isn't that old. I'm confident parts are available and you can get it fixed and overhauled at Thong Sia in Central Plaza, KL. I doubt that Thong Sia does case & bracelet polishing so you probably need to send it elsewhere.

The model code for your watch is SND119P1.

Blind luck.

Final Results of my 7 months old SNK807K1 Comparative Test with my phone.



The phone that I am using for comparison is consistently +6 of standard time. Not sure what happened on the 31st.
Checked yesterday and today -> Still +6 of standard time.

Summary:
A Seiko 5 is a reasonably priced watch that will complement a mobile phone for daily timekeeping and scheduling.
A new one will normally run fast +10 or more (set by the factory) but after a few weeks of daily use, the daily error rate will be lower.

I usually wear mine 12 ~ 14 hours per day.

There are claims of super accurate Seiko 5 on the net. But it all depends on how one wears the watch.
From personal experience, worn 4 ~ 8 hours daily with the watch positioned to take advantage of the watch's balance positional error it can be regulated close to zero daily error rate.
Tried it for 2 weeks.

Finally, my 16 year old SKJ006P1 Seiko Kinetic that was overhauled last year was -4 seconds of standard time after 31 days and my 20 years old Tag Heuer quartz was more than 12 hours behind.

I prefer not to disturb this thread. Let's continue the discussion <here>

Looks like you have an allergy to Seiko watches. The noise is there only when I look for it when wearing the watch. Otherwise, it doesn't really bother me.

Some noise or I prefer "sound" is inevitable due to the design and function of the Magic Lever winding system. It is was first designed in 1951 and is used in the current 7S26 all the way to 8L35 movement. It uses only 4 components for the winding mechanism. Compare that to the conventional winding gear design with reverser. The Swiss have something similar: Pellaton winding mechanism that uses more parts and jewels to achieve the same function.



This is also one of the reason why I love Seiko watches.

Like the theme song sung by Carly Simon from The Spy Who Loved Me:

Nobody does it better
Makes me feel sad for the rest
Nobody does it half as good as you
Baby, you're the best.........



If you want a mechanical Seiko with conventional winding system that is quieter, go for Grand Seiko 9SXX movements.

Yeah, I think its too big. The diameter of the wrist viewed from the top ideally should be more than the lug to lug measurement of the watch. Why don't you try out the SBDX001 Marinemaster? It has the same lug to lug length but appears smaller than the Sumo.

Some stores allow you to swap the strap with another watch on display. As long as it is genuine and you got a fair price for it, its not really a big issue anyway.

The important thing is to do is to research before buying.

What do you mean cannot afford an automatic? Seiko and Orient sells automatic watches for less than RM500.

Found one and pulled the trigger for my collection.



Better late than never.

Locally. I think there is still one more in the wild.

NOS. Yes, its worth it.

The pic isn't sharp. Is it a Seiko 5 Quartz and is it in working condition?
It's possible but depends on how much that watch is worth to you and whether you are willing to pay for it.

I think that watch uses a 5Y13A movement.
Post the Serial Number, Caseback Number and Dial Code. I'll try to find the model no. May take sometime though.

The strap used is common for several Seiko models. The code for that resin band is 4KR3JZ. I have 2 but unfortunately not for sale.

For originality, Sumo does not come with a resin band.
The one that you are using is 4HX0JB. Get it from an authorized Seiko dealer or directly from Thong Sia.

The model no. for the watches are:

6309-7040 - SDE091
6309-7049 - SDE095

Post the caseback no. (XXXX-XXXX) at the back of the watch and I'll try to assist.

Congrats. Planning to get a few 7S26 watches too. Just curious, who took that picture? And why date change in the middle of the day?

Yup, the 7S26 and 7S36 has been discontinued. If I'm not mistaken, it was introduced in 92 or 93. Usually, Seiko movements have a production lifespan of 10 years. Due to its demand, simplicity, reliability and accuracy it has been in service for 20 years.

Most parts are interchangeable between the 7S26 and 4R36.

Next longest in service would be 5M42 & 5M43 Kinetic movements. A few years more, it can surpass the 7S26.

According to the tech specs:
Fully wound, the 7S26 has a power reserve of 41 hours + in dial up position. The mainspring barrel takes 8 turns to fully wind it up manually with a screwdriver. The rotor needs to rotate 1800 times to fully wind the mainspring from fully winded down position.

Putting a day date dial 7S26 onto date only movement 6R15 won't be nice due to the empty space for day wheel.
Seiko does not and will not sell complete movements. The only way you are going to get a complete Seiko movement is to cannibalize another Seiko watch. The new monster would be a perfect choice since the crown is at 4 o'clock similar to SKX007.
The alternative is to get a movement from TMI. NH36A = 4R36A (Minimum order 100 pcs) Only caveat, no Seiko markings on that movement.

NH36A is configured for 3' o'clock crown position. Putting one an SKX007 means the dial won't align correctly. The dial feet needs to be removed and use adhesive stickers to attach the dial onto the movement. Other than that, need to change the crown winding stem, else can't fit the part for hand winding nor for stop seconds function.

Nice. RRP RM 2,499.00 is a bit steep IMHO.


Can you please post the caseback no?

After doing a bit more research, it seems that 7S36 movement with crown configuration @ 3 o'clock is discontinued while the one with crown configuration @ 4 o'clock is still available. I suppose this makes sense since 4R36 watches are more expensive and by totally stopping production of 7S26 and 7S36 will remove Seiko from the lower end of the market.

7S26 and 7S36 is almost the same except for the extra 2 jewels. <Link> Click and scroll down

In a way, 7S26 still soldiers on....
