Seiko 5 Cal.7009A Lube And Crown Function Advice Please

[tpt]

Could I ask for a little help please,

I'm looking at a pdf of a movement I'm learning on, and am hoping someone can tell me the equivalents of these oils listed:

 

Mobius A

Seiko oil S-4

Seiko oil S-6

 

 

I have at my disposal:  Mobius: 8300, 9010, 9104, 9415

 

 

Also... before disassembling the watch; the crown would not wind the main spring and there seemed no day of the week advance on the crown either. simply 2 positions. date advance and time adjust.

I could see nothing broken or missing inside and am now thinking, perhaps that's as it was made. It had an auto wind mech. so perhaps Seiko decided it wouldn't need hand winding???

 

Am I very much mistaken?

 

many thanks

I use this oils to Seiko.

 

Mobius A = 9010,

S-4 =  D5 or HP1300,

S-6 = 9501 or a other stem grease

Most Seiko auto's until recently were just that - auto's, no way to hand wind. Just give it a gentle side to side shake for a short while and its good to go. The day will need to be set by turning the hands between 10 pm & 2 am until the day is selected.

Hi Tim,

 

I don't know what the Meobius equivalents are for the Seiko oils but what you've got will certainly work.

I would use the 8300 on the main spring (very thin wipe over the spring before reinstalling into the barrel), the keyless works, and the canon pinion, 9104 (or HP1300) on the low speed high torque pivots like the barrel arbor pivots and centre wheel, 9010 on the higher speed lower torque pivots (basically everything else but don't oil the pallet fork pivots), and the 9415 on the pallet stones. You should also use a braking grease (something like 8213) on the barrel walls before installing the main spring, other than that you should be good to go.

Other opinions will differ.

 

The 7009, like many of the Seiko calibres found in the 5's doesn't have manual winding, it is an auto only but the winding efficiency is very good and it shouldn't take too much movement to get it running. Also the quick set for the day I believe is by pushing the crown in, it advances 1 day for each push.

 

I'm sure that someone will correct me if I am wrong.

Marc is correct.

Pushing the crown in from its normal position advances the day wheel.

I stand corrected gentlemen. I must admit that its about the only Seiko caliber I haven't had the opportunity to wreck err restore to its former glory...yet.

Thank you very much.

I'm learning lots!

 

now to get it back together...

6309 is quick set too.

Agree with lubes. 

If its like a 6139 which I serviced recently then the quick set is Push crown fully in to advance day; push crown in to 1st posn to advance date. 

The autowind system is very good but you can wind the mainspring up a bit quicker by turning the screw holding the winding gear to the barrel.  This is accessible via a hole in the plate.  Turn it slowly (to avoid overworking the autowind pawls and click) with the widest screwdriver than fits until it gets to feel quite tight (don't overdo it as you may damage the screw slot or overtighten the screw and break it !). The autowind will then have less to do. Useful if you want to regulate right away.

I got my s-4 and s-6 from the bay...not too bad considering they come in a "big" plastic container and last for quite a while...
