We usually change faulty movements only.
Finding rest of the watch for good movement is not worthy any efforts.
BTW - movment Y573 is discontinued

Yep, very old that one.
I've had little success sourcing cases for even 5-6 year old Seikos,
but it's always worth a shot if the customer insists.
Certainly not worth it, the case would cost about(and maybe above)
half the value of the watch.

If Lorus (which belongs to Seiko group) has the same algorithm for serial numbers as Seiko, you may assess manufacturing date by 3 most left signs of it's serial number (provided your Lorus has serial number on back case).

Seems your Lorus has no serial number. Dating by S/N is impossible.

Hard to say. I can't even recall what the 573 looked like, but i think
Seiko/Lorus stopped the Y designation in the mid-late '90s. So if i'm
correct(and i think i am, seeing that my oldest,year 2000, movement
catalogue only lists 3-4 *substitues* for the Y movements and couple
of Y15xs ), it's at least 15 years old and perhaps up to 20-25.

So the s/n on my Seiko starts with
822
Does this make it 1982? I have been wearing it for so long, I forget when I
bought it :)
There is another 6 digit number that starts with 150?

If you can't fix it with a hammer.......you have an electrical problem

no, only the first 2 digits, you have to guess the decade, so 82 would
read as 1978 February, or 1988, 1998, 2008 etc.
Here is an excerpt from www.brittons-watches.co.uk:
"Seikos have the date of manufacture written into the serial number which is engraved on the back of the watch also the movement-model numbers are also engraved onto the case back. The first number represents the year and the second number (or letter) represents the month (1-9 for Jan.-Sept. and O,N and D for October, November and December).For example if the serial number was 864825 and you knew the watch was made sometime in the 1970's it would indicate it to be made in June 1978. You have to know the age of the watch to the nearest decade so sometimes it can be a little bit difficult. Usually the case style or the introduction dates of the movement can help to narrow this down though.
General rule for manufacture month/year is to look at 1st digit of serial # to say what year within decade. Then look at 2nd digit/letter to tell month. For month, 1-9 are Jan thru Sep, with 'O' for Oct, 'N' for Nov, and 'D' for Dec.
For decade itself, you have to know the actual production dates of the movement itself. If you don't you could e mail Seiko customer service in (Japan) ,quoting model and serial numbers and they should be able to help,here is their e mail address below
Thank you for the info. It's quite possible it's 1978 when I bought it.
Thank you for this answer, I have emailed Seiko and will let you know what
they result.
Regards,
That'll be interesting if you could. I tend to think that Lorus was
not around yet in the '70s.
I have to remap my memory. :)

it wasn't, excerpt from this page,

``````````````````
Launched in 1982, and now marketed internationally, Lorus is a brand of
Seiko Watch Corporation,
``````````````````
so his watch would be 1988 at the earliest.

But this time we are talking about Seiko belonging to PV.
Lorus in question has no serial number on backcase making manufacturing date estimation impossible by this method.
BTW - I've gotten an Alba watch (as Lorus belonging to Seiko) and there is serial number on back case - 6 digits as in Seikos.
I probably shouldn't have hijacked the Lorus thread, but the link to Seiko
caught my eye.
Here is the response from Seiko regarding my watch
Thank you for your patronage of SEIKO product.
We are unable to give the exact production date, but we inform you that your
watch
(Case no.8223-7149) was produced in early 1980's.
And almost thirty years later, three chrystals, one new face and numerous
batteries it's still running. But due for a new crystal soon

Hi PV,
probably I wasn't clear enough.
8223-7149 is not serial number.
In fact it is combined movement type 8223 and case/dial type 7149.
Here you can find specification of your 8223 day/date movement:
http://www.watchuseek.com/seikocitizen/SeikoTechnicalManuals/8222A_8223A_8229A.pdf
Bearing in mind previously mentioned 6-digit number starting with 150XXX (that's serial number) and Seiko reply you may be sure your watch was manufactured in May 1981.
Wear it in good health :-)
