Bought today - my first mechanical 400 Day. Lovely glass dome, but minus suspension guard and with broken suspension. I'm sure Horolovar can find me the suspension, and from what I've been reading here maybe a mainspring, but they don't list a guard. Ideas welcome!

Also welcome would be any advice, and particularly information on the likely type and date of the clock. For example, is the dial enamel or paper? From my day spent reading on this forum, the movement seems to fit with 1393B and 1471C in the Guide, and probably others. The clock is 6 1/2" high over the dome and the base is 5" diameter. The plates are 42 x 53mm, with a gap of 20mm between them. Please note, the fingerprints on the rear plate are not mine!

Welcome to 400-day clocks, David! I would say given the near exact match to 1393B, that is the plate. Only difference in 1471C is the variation in the lettering and logo. I don't think the dial is paper...I think it is painted on. I have something similar but plate 1396. It won't run for more than 3-4 months, but given the tiny nature of things and the pin pallets, it might be a while before I decide to try and clean it up. I wouldn't think you need to replace the main spring, but if you dive in maybe you'll see a reason for it. Typically the main springs are either dry or over oiled.

As for the suspension guard, I find they are part good and part curse! Anyway, here's the back of my clock so you can see what a guard likely looked like.

Yes, welcome to 400 day clocks. I find the guards a pain as well. Just when I think I have one going well, I need to adjust something and have to take the guard off. I can see why they are easily misplaced or lost. I have been bagging mine with labels or keeping them loose at the bottom of the clock. I don’t see them as essential, so no longer find it necessary to replace them when a clock comes my way without one. I would agree that the dial is painted. Also agree mainsprings are usually fine, just dry and dirty. The midgets are lovely little clocks in all their styles. You might find yourself ending up with more than one.

Thanks, Kurt and tracerjack, for a quick response and clarification on the plate and the dial. I just bought an NOS Keininger movement which turned out to have a paper dial, so I'm wary about these. Maybe I won't order a mainspring initially, although one issue for me is that postage to New Zealand often costs more than the parts I buy. My main concern about the guard is that it seems (I've never seen one in action) to retain the top of the pendulum when it is lifted for transport. Not that I plan on moving it around, but I've seen enough on this forum to be wary about breaking suspensions. Incidentally, I intend to order a complete suspension, even though I have all the parts from the old one - it seems a safer way to start my exploration into the mysteries of the 400 Day. My previous experience is limited to repair (really cleaning and a little lubrication) of the stopped pendulum of a Schatz quartz Typ 12, and the conversion of another derelict quartz base and dome to house a nice little movement bought in Budapest.

I always use the original top bottom and fork because I feel it is nice to keep the clock as original as possible, also make sure you have zero friction because the small torsion clocks are very finicky .
Good lock Dell

Thanks, Dell. I will order both an assembled unit and spare spring/s, so that if I can't get it right I can fall back on Horolovar's expertise. Looking at the fork on mine, it could do with polishing inside.

I didn't see it in the pictures, but does your base have a lever that lets you slightly raise the pendulum? If so, then it would be used to slide the hook up inside the guard for general moving. It wouldn't be enough for shipping in the post, but I suppose moving it around the house it would help. I usually just grab the pendulum with one set of fingers and then pick up the clock with the other hand.

Yes, Kurt, it does have that lever. I've managed to hide it behind one of the weights in both photos.

Thanks, David

Well, with postage being a factor, you might want to get the spring just in case. I often have to order parts I only think I might need to justify the shipping cost.

Thanks for #9, I'll order a spring. And some Simichrome as well - despite postage costs, it will be cheaper than buying it here. The base cleaned up surprisingly well with acetone and brasso, but everybody seems to like Simi for a finish and lasting protection.

I've been looking around the net for a guard and I've just found a clock in the UK which seems in poor shape, but has one. Catch: 50 pounds postage here! Maybe not.

Regards, David

My first Horolovar shopping experience, too. Great! Lori verified that I have a 1393B plate and identified the mainspring, suspension unit and springs I need. John dug around in dark corners until he came up with a complete suspension guard assembly for me. They're on the way, with key, long - reach oiler and Simichrome - you guys have talked me into trying Simichrome instead of the Autosol I can buy cheaply just round the corner..

Yes, I'm definitely going to fit the guard first up because after the first assembly I'll never need to get inside again..... Actually, from what I read on this Forum, that could be a bit over ambitious. We'll see. When the parts are here and I've done my best I'll add a bit more to this thread.
