Richo "dynamic Wide 9" Service Walkthrough

Richo "Dynamic Wide 9" Service

 

New watch to practice on came in the mail today. 

 

 

It was a cheapie on Fleabay; but has a Day/Date Complication, with a pusher advance for the date, that I thought would be a nice advancement in my training.

 

 

There was two other components in servicing this watch I need practice on: springs and incablocs ... and this movement has them in spades!  And to stretch myself further I choose this movement because it uses a copy of the Seiko DiaShock System, this time with a more complicated three prong keeper; as apposed to the dual prong keeper in the 7S26A Movement I completed previously.

 

 

I couldn't find any service information on the movement, so I just went with skills the Lord has given me, experience from the past 3 movements and reference photos.

 

 

First Dial and Hands are removed

 

 

Remove the Date Ring, which is only held by spring tension on the Day Jumper.

 

 

Next remove the Date Dial Guard

 

 

Remove the Date Ring, and the Calendar Works ... Note the spring for the Day Jumper, and one also for the Date Jumper.

 

 

Continuing, remove the Date Drive Wheel (which is in two parts) , The Motion Works, and the Cannon Pinion.

 

 

Remove the Setting Lever Spring, and the cover for the Date Advancement Pusher Works

 

 

VERY carefully remove tension from the Date Advancement Spring, it is under a lot of load and is "S" shaped when removed. Next remove the Date Advancement Works.

 

 

Unload tension on the Yoke Spring, and remove the Yoke and Setting Lever.

The Clutch Wheel and Winding Pinion will now fall out once the Stem is removed.

 

 

Release the spring tension from the movement

 

 

Remove the Balance

 

 

Remove the Pallet Fork Cock, and Fork.

 

 

Remove the Ratchet Wheel, Crown Wheel, and Click.

 

 

Note the orientation of the Click Spring and remove.

 

 

Remove the Train Wheel Bridge

 

 

Remove the Fourth Wheel, Third Wheel and Escape Wheel.

Sorry I forgot to get this picture, I got a little engrossed in my work  ^_^

But there is nothing special about the layout, just your standard 17J configuration.

 

Remove the Barrel.

 

 

Remove the Centre Wheel Bridge.

 

 

And lastly remove the Centre Wheel

 

 

Time to clean the parts ...

 

 

All the parts clean and ready for reassembly.

 

 

Reassembly is just a complete reverse of the previous procedure.  The only difference is the incablocs, as they are a DiaShock System, and the Keepers are VERY small indeed.

 

 

 

As shown the 7S26A Walkthrough, use a plastic covered Paperclip as a special tool to hold the Keeper in place while your remove and install.

 

 

I hope this is a help to others, and I'll continue to post up the movements that I work on, so as to create a library of walkthroughs for many movements, and as a catalog of my self-training and advancement in this wonderful trade.

Great idea Lawson. I'm sure it will be very helpful for reference regarding movement configurations and problems encountered.

Just finished regulating the watch.

Not bad for a AU$30 Cheapie off the Fleabay :)

nice one... was it running on arrival? Would have been nice to compare the timer tracks before and after.

Again well done Lawson,  you are progressing in leaps and bounds and the write-ups are very interesting.

Just curious as to why the dial says 21 jewel yet the movement says 17 jewel.

One word .... Fleabay :p

Good point Anil.

 

Yeah it was running.  From memory it was -25 to -30s/d (wavered a lot; but not a complete splatter pattern), and Beat Error was 3.2ms. 

Next time I'll start with a picture of the starting condition of the movement on the Timegrapher.

Terrific, thanks for sharing Lawson.  Very much appreciated.
