How much gold is in a pocket watch?
We receive countless inquiries with questions about the amount of gold in pocket watches. Smart folks with plans to sell want to know how much gold is hiding in their pocket watch before they start offering their timepiece. Most people know that a watch’s gross weight doesn’t equal its gold weight. But how can you find out how much gold was used to produce your pocket watch?
Basically, there is just one way to achieve accurate weight information:
TAKE YOUR WATCH APART
Take your watch apart if you have the tools at home. Or, you can ask a watchmaker to take it apart or mail it to reDollar to get the non-precious parts separated from the gold. We’ll provide you with photos of all parts on our laboratory scale so that you can understand exactly how we calculated your purchase offer. reDollar’s motto is “Like A Bank,” which means that you can fully trust our experience and reliability, and know that we’ll recover every tiny piece of valuable gold for you.
Let’s take a pocket watch apart
The really heavy part of a pocket watch is its movement. We took several pocket watches apart to get some information about the movement’s weight. We also disassembled a hunter pocket watch and weighed all parts to do a case study.
Part | Weight (grams) | Percentage (%) |
Whole watch weight | 93.89 grams | 100% |
Movement | 54.34 grams | 57.88% |
Crystal | 2.63 grams | 2.80% |
Crown’s gold | 1.17 grams | 1.25% |
Crown’s base metals | 2.71 grams | 2.87% |
Inner metal frame | 6.72 grams | 7.16% |
Case’s gold (total gold weight) | 30.02 grams | 31.97% |

The Experiment
We are taking apart a South Bend Watch Co. 17 Jewels Double Roller pocket watch with a 14K Keystone case. It’s a private label watch originally made for M.M. Bovard & Son.
The movement is the heaviest part
It’s absolutely necessary to remove the movement to find out how much gold is in a pocket watch. It’s very easy to do, and the process will NOT cause any damage to the watch if professionally done. Depending on the watch, two or three screws hold the movement in place, and removing those screws will separate the case from the engine. Be very careful and do not touch hands, wheels, or other sensitive parts.
We took 12 different-sized pocket watches apart to give you an idea of the weight of your movement.

How much gold is in a pocket watch?
It’s very important to know that the gross weight of a pocket watch is not the weight used to calculate the value of your watch. It’s easy to calculate the value of a wedding band, for instance, as you can just put the ring on a scale and use the displayed weight to do the math. That’s not possible with a pocket watch, as you need to deduct the weight of non-precious parts before you can find the value.
Non-precious parts are
- the movement
- the inner frame holding the movement in place
- the crystal
- most parts of the crown
Precious parts are
- the case
- the gold surrounding the crown
Case without movement
How much gold is in a pocket watch case?
After removing the movement, which is considered the heaviest part of a pocket watch, we still can’t use the net weight to calculate the value. There are still non-precious parts present: the inner frame holding the removed movement in place and most parts of the crown. But even NOT removing the inner frame and the crown can give you a better idea of the gold’s net weight.
The pocket watch case, with movement removed, weighs 39.45 grams, which equals about 42.02% of the watch’s gross weight. So you see, we already “lost” over 60% of the pocket watch’s total weight.
Additional knowledge!
Pocket watch cases marked “14K 25 Years Warranted” are gold-filled and not made of solid gold. Pocket watches marked “14K Warranted” without “25 years” can be considered solid gold.
Weighing the movement
What’s the weight of the movement?
As already discussed, the weight of a pocket watch movement is a significant factor when it comes to finding out how much gold is in the watch. This movement weighs 54.34 grams, representing 57.88% of the watch’s gross weight. Depending on the size of your pocket watch, movements usually weigh between 40% and 70% of the total weight. It’s very important to remove the movement to get a clear idea about the gold weight.
Fact Summary
- Movement diameter: 43.08 mm = 1.70 inches
- Movement weighs 54.34 grams = 34.94 dwt
- Movement presents 57.88% of total weight
Crystal & Gold-Filled Frame
What’s the weight of the crystal?
The crystal of this pocket watch weighs 2.63 grams, including the frame. In that case, the frame is just gold-filled, so we cannot add it to the total gold amount. Some pocket watches also come with a solid gold frame. It’s very important to know that this crystal was made of plastic replacing the original crystal. Plastic crystals are usually lightweight in contrast to old, heavy glass crystals.
How can you find out if you have a glass or a plastic crystal? Gently knock on the crystal. While glass will give you a nice sound back, plastic will remain almost silent, making only a dull noise.
Disassembled pocket watch case
Other non-precious parts
There is a steel frame placed inside the case to hold the movement in place. This steel frame needs to get deducted from the total weight as well. This particular frame weighs 6.72 grams (= 7.16%). Besides the frame, there is a steel component inside the crown. This steel pin is responsible for winding the watch as you move the crown. We took the crown apart to weigh those parts (the winding pin and another steel component inside the bow). The non-precious parts of the crown come to 2.71 grams (= 2.87%).
Non-precious parts
Inner steel frame, crown and bow.
