About 5 months ago I bought this clock new. I've posted about the purchase decision in another thread. I now have some questions which I thought is best asked in a new thread.
Here are a couple of photos taken today.
The clock is made of Linden wood and sounds fairly pleasant when gonged.
Over the last 5 months I've been trying to figure out its behavior, and every now and then recording my findings. Last month's report is as follows:
On 3rd September I rewound it fully and set it a minute fast.
On 14th Sep (11 days later) the clock had gained 5 minutes (6 minutes faster than the real time). On this day I reset the time to match the real time.
On 2nd October (18 days later) the clock had lost 2 minutes.
So the clock gains about 3 minutes in a month, and it seems to go fast within the first two weeks (gains 5 minutes) and slows towards the end (loses 2 minutes).
I've now rewound fully and set it for 1 minute slow. If September behavior is consistent then at mid month it should be 4 minutes fast, and at end of the month it should have come down to just 2 minutes fast. Fingers crossed!
Not complaining but would this sort of changing inaccuracy be normal? I don't know anything about clock mechanisms, but I would have thought that the inaccuracy would be constant across the entire power delivery. A bit surprised it ain't so.
I've tried to keep the humidity inside the case down by placing a couple of moisture absorbing pads inside. Hopefully that will help.
I guess at some point I would need to service the mechanicals. What sort of maintenance would I need to do and how often? Can I do it myself with basic tools? Any advice is appreciated.
