Hi,

I’m looking for a case ring MR556 for a case nbr 827. Bulova Sea King 11ANAC N0

I’ve tried eBay but no luck.

As an alternative I’d be interested in a case and caseback and ring that would fit this movement and dial. 

lastly, any suggestions how to case up the movement and dial without a case ring are welcome.


Thanks

Is it the Golden Clipper 'G'? It looks like the MR556 was only used in 2 Bulova cases so there may not be many floating around. If you have a 3D printer I can take measurements of mine.

Thanks for the offer! I actually found a NOS one today at McCaw Supply (Toledo OH). Was their last one, so feel lucky. I was thinking this was an opportunity to explore the world of 3D printing but looks like it will have to wait for another project. 
 

Happy Holidays and thanks again for the offer.

Good stuff. Did they have it listed on their website or did you have to call them to do a stock check?

I always call them. They are very old school—Their site really doesn’t list much of anything except some tools and supplies and their search function isn’t very effective.

    • Hello and welcome from Leeds, England.  Photos please. 
    • Hello and welcome from Leeds, England. 
    • This is the old/first(?) way for making a mainspring for an automatic. "Evolution-wise" it is an logical first step forward from a standard spring. Usually these are indeed replaced with a new spring with an integrated/fixed bridle. Lubrication as you would do with any automatic.
    • Thank you. I was informed it was a cheap worthless Lack watch from India. It’s in a small mens watch looks to be around 1930 odd   Cleaned the movement and it’s going really well. Keeps good time.  This is a great site. Mystery solved. I’m obliged. 
    • I'm working on a Schild AS 1250 (a 'bumper' automatic) and it's the first time I've seen a mainspring like this. It has what looks like a regular manual-wind mainspring with a 'hook' at its outer extremity. On a manual-wind watch that 'hook' would engage with a 'hook' in the barrel wall to prevent it from rotating. However, the AS 1250's mainspring does not engage directly with the barrel but rather with a 'sliding bridle' that sits between the mainspring and the barrel wall, and evidently facilitates the slip necessary in an automatic. I'm not sure what advantage this two-piece configuration provides, but it highlights a gap (one of many) in my horological knowledge. I'm not sure if 'hook' is the correct term as used above, but please see photo below to see what I mean. Therefore, two questions please. 1. What is the proper way to lubricate a barrel from an automatic watch with a sliding bridle? My guess is the same as any automatic ms/barrel (e.g, a few dabs of braking grease on the interior barrel wall). What do the experts say? 2. I purchased a Generale Ressorts GR3472X mainspring, made for the AS 1250. It looks like the bridle is included and I don't need to salvage and re-use the old one. Is this a safe assumption? Thanks for the advice. If you have any other wisdom you'd like to share about separate sliding mainspring bridles, I would be very interested. Cheers!
