I'm sorry I'm totally new to this and didn't know I have to set beat, it was working great and just recently started to gain time so any help would be appreciated

A photo of what you have there would help, mainly the movement.

Your symptom is a very common one. It's often caused by a worn escapement.

Most of the time the flaw can be corrected (temporarily) by moving the pallets slightly closer to the escape wheel. The escape wheel teeth MUST always drop onto the slightly curved upper (dead) faces of the pallets.

The "beat" on your clock would most likely be set automatically.

That's a very different clock from what I was thinking ... Disregard previous post.

Your clock is at least 33 years old, a good bit past it's service life. When a Hermle balance wheel clock starts to wear badly they loose power and this causes them to gain time.

So, I would say that your clock will need a complete overhaul, or a new replacement movement. In my shop, the repair cost is usually close to the replacement cost. So, I replace most them.

This model was made for a long time and some of the older ones are actually a better candidate for repair than the newer ones.

The age of your clock can be determined by the info at the lower right corner of the back plate.

That little balance wheel should turn about 360°. If Willie's assessment is correct, it will be turning considerably less than that. It's a way to verify what he posted, so you can plan your best options.
