I look at classic watches like classic cars. Why throw away a beat up watch and rusty car. I rather restore a watch or car with aftermarket parts then to leave it on the shelf or junkyard. I wouldn't consider a watch or car fake because it has aftermarket parts to bring it back to its former glory.

A letter N after the first number does not mean its a fake or aftermarket, it stands for November, you can also get a D after the first number and guess what thats stands for? I believe you are refering to the 6N3147 serial number that the reproduced/fake case uses, it is however a correct serial number format used by Seiko but this one is what is used extensively and is poorly stamped.

What of it is 'J' ? June or July ?

[@Laptech7]

​@@siddhunkarthik From 1966 to present day Seiko use a 6 digit serial number of which the first number is always the year (not the decade, you work that out from the movement production years and case number) and the second number is always the month. Seiko use 1234567890ND to indicate what month and nothing else, You do not have a Seiko with a J as its second digit of its serial number, even the "fake" Seiko has a correct serial format. June would be 6 and July would be 7 btw

One of the only designs that came out of the 70’s in less we are talking 1970 maybe 1971 that was the end of the high horse power muscle cars. Great video cool Seiko’s.

[@scottmaeker6437]

The first number on the case back denotes the year that it was produced, the second letter denotes the month in which it was produced in the case that it was produced in December it will have the marking D or N

Lots of great information. I own a Seiko Helmet and love it.

[@unclejack168]

Very informative thank you.

[@gugunarief]

Are you sure it is in the Seiko 5 family? Beside there is no 5 logo, the movement is clearly not in the family.

[@pantarhei-watchesbeyond460]

This is what I read =) source seems trustworthy, regards,

[@Laptech7]

Not sure how you can say the 6138 movement is clearly not in the Seiko 5 family?
Seiko 5 was first released in 1963 and was named that by Ren Tanaka himself as he felt the name Five and the fact that its an uneven number would make it youthful and dynamic. Badges were popular back then so he decided to use it as a symbol for this new line of watches, Only after release it was added that it stood for 5 of the watches characteristics or attributes and said it stood for. 1- Efficient automatic winding 2- Day and date in a single window 3- Water resistance 4- A design with a masculine charm 5- Reasonnable use of jewels.
Later people have added (not Seiko) that a Diaflex mainspring and diashock jewel settings were part of the 5 and even Wiki says that telling the time is 1 of the 5..
On Seiko's website they are currently saying the 5 stands for 1- Automatic winding 2- Day-date display at the three o’clock position 3- Water resistance 4- Recessed crown at 4 o’clock 5- Case and bracelet built for durability. Lets just say its changed over the years and the 5 means many things and also nothing lol

[@kenlipper874]

Thanks for the video - very informative!

[@ModernTacticalShooting]

according to seiko serial numbers could have a number then letter for example 6N7694 made 1976 N stands for November

[@kevinjamesdawes7223]

So essentially there's no way to tell the difference. They aren't expensive anyway and if seiko can't be bothered to make them then somebody will. If they put a seagull chrono in then it's better than the original.

[@truxton1000]

Seagull better? No.

[@scottmaeker6437]

The fishbone bracelet we'll have a stamped number if it is an original. Just because the clasp says Japan sea does not make the actual bracelet original

[@scottmaeker6437]

The letter N in all Seiko case backs denotes that the watch was made in November

[@BiffTannenBTTF]

Wearing mine now 👍

[@florinflorin249]

can you tell smth about how the brushing and polishing is supposed to be on the case?

[@fernandopaseri3070]

Jejeje este seiko me gusta lo usaría 3d mui bonito y varonil pero no se compara von gk que tuve de alto calibres tipo joya asero inoxidable esfera anbar estilo de metal grueso dava personalidad jejeje 🙈 era unico estilo de los 70

[@brucecoleman6014]

I had one years ago, but I sold it. Wish I had it back

[@siddhunkarthik]

In India, almost all kinds of vintage watches are serviceable. The watch makers , repairers are very skillful in it.

[@pantarhei-watchesbeyond460]

Good for you =) adding to it I would say India has one of the biggest spare parts markets for vintage Seiko watches in the World =) regards, Adam
