How will I test my product

So originally I wanted to survey people about my product against my design specifications. My design specification are:
  • Size of a shoe box (excluding Pendulum)
  • Made mainly of wood
  • Looks just like the design
  • Shows how the mechanics of a clock works.
  • The weight has to be easy rewindable.
So I was planning on asking questions like:
  1. Is the clock (excluding the Pendulum) about the size of a shoe box?
  2. Is the clock mainly made out of wood?
  3. Does it look just like the original design?
  4. Does it show how the mechanics of a clock work?
  5. Is the weight easily rewindable?
But for people to answer some of these questions they would either have to see the product or know how it works. As I cannot bring the actual product around with me, or have time to explain exsactly how it works I decided that I will not do a survey. I would also need a lot of people to survey which is very inconvenient and time-consuming.
I decided that I would just reflect myself on how well I have done in my design specifications. As most of them are either common-sense or measurable I believe I can decide myself if I have achieved the specification.

I will check myself if I have reached the specification by:

Measuring the outline of an average/random shoe box, and measuring the outline of my clock. I will allow myself a 10cm margin of error.

Other materials are allowed to be used in my product, but it has to be mainly wood. If I have achieved this specification mainly relies on common sense.
Looks just like the design is an easy one. I have in no aspect in any way changed my design compared to my final product. The slightest change causes this specification to fail.
It should show how the mechanics work
I designed my clock in such a way that it will show how the mechanics of a clock clearly. If I will stick to the design then this specification will automatically also be achieved.
Then again, I designed the clock in such a way that the weight will be easily rewindable. So if the design works out OK, then I automatically achieved this too. But if I don't achieve the 'just like the design' specification I will time myself rewinding the clock. If it takes takes 60 seconds or less in a normal (not rushing) speed, I have achieved this specification.


If the majority of the questions are answered with yes... then I can proudly say that I achieved my goal.
