...one of the pages I stumbled upon yesterday searching for the banana, it looks like your movement and watch...note the parts lists at the bottom, which helps confirm compatibility...

Andy, the first link looks different to mine, the escape wheel jewel mounting is different.  The second link showing the 1960 Seiko Laurel looks pretty close, although this one has a different balance shock protection than mine.  Just grabbing an image of my dial.

 

I think thats M14017 at the base of the dial.

I wrongly presumed the dial was blank and that's why you were asking the question.

This now raises the question as to which is the correct Hour Wheel

255.392 or 271.570

[MikeEll]

yeah, thanks Andy.  Hope I'm not coming across as ungrateful, I really appreciate the help.  Just that I've been burned before when I've assumed movements look the same

[rehajm]

...and sorry for inserting myself into this thread but for posterity be warned, the lack of reliable information on these older Seikos is a bit maddening. When the movements don't have hallmarks but sometimes have caliber numbers and sometimes shikona and sometimes one name used for more than one movement......

Bestfit tells the story- just look at those calibers...

The fact it has a Marvel Dial and a Marvel Movement means it's a Marvel.

The question is that information on the original Marvels is none existent
and only information on the subsequent movements is available.

I've got a 271.570 Hour Wheel somewhere so will find it and see how it compares to yours.

Nothing to be sorry about. It's an open forum and anyone can comment.

@MikeEll just wondered if you'd had chance to compare these yet?

[MikeEll]

Ah, sorry just noticed your reply.  I’ll take a look today.

[MikeEll]

The canon pinion looks the same, and the hour wheel is very close.  Same number of teeth but 1.40mm height.  I’d say probably the same parts.

I'd say for the price they'd be worth a shot.

Yes definitely, thanks for that

[MikeEll]

I've ordered a couple of those, fingers crossed

 

[MikeEll]

Update, they were a perfect fit.  Nice one.

Thanks @AndyGSi and @rehajm

Turns out I also need a balance complete for the Marvel.  I discovered a crack in the hairspring collet and so can’t adjust the beat error.  The balance for the 560 (part number 310570) is in stock but not sure if it will fit.  Any idea?

As they share the same balance staff I think the 560 balance complete would be your best option.

Edit

Are you sure the collect is damaged and it's not just a split one?

Yeah, it’s definitely cracked.  I could probably glue it, but more trouble than it’s worth.  A new one is £14.

 

[AndyGSi]

Yes, I see now that it's cracked but wasn't sure if you were just referring to the split opposite it.
