Project THOR – Design Thread 6
Case Material and Finish
So far we have established five key elements of the Project THOR design through our discussions and votes: our watch will be an original design inspired by jet-age cockpit clocks, limited to a cost of €1000, and will be powered by a Soprod 9335 GMT movement housed in the Military 42 case.
The next step will be to determine the material the Military 42 case should be made from, and which finish it should have.
Take time to examine the following two lists of available options and decide which combination of material and finish would best convey the look and feel of an aviation cockpit clock. Under the lists you will find notes from Triton, our project designer, who addresses this design step; you should carefully read his comments and factor them into your decision process.
Finally, we ask that everyone keep the discussion on topic. Other design matters, such as the bezel and crown, are not a part of this step and will be covered in a subsequent design thread.
Available materials for the Military 42 case:
- Stainless steel
Available finishes for the Military 42 case:
- Brushed (matte look)
- Polished (glossy look)
- Media-blasted (textured look)
- DLC (black)
- PVD (multiple colours available)
From the Designer’s Desk:
"The Military 42? Good choice! The case is readily available in stainless steel, but I've also included bronze as an option. Bronze would be a special order, but it would be available for when the project reaches the production stage.
The bezel on the Military 42 is not part of the case, so it is possible to design one different to the one currently being used. Adding a turning mechanism is not an option as too many changes would need to be made to the case itself.
Concerning the budget, bronze as a case material is more expensive than stainless steel, roughly 50% more, so I would advise against wasting part of the limited budget to hide the bronze by covering it with a tough, scratch-resistant DLC coating. It would take an immense effort to achieve a worn-off (patina) effect with a DLC-coating.
The choice of movement used up more than half of the budget already; however, the Military 42 case is fortunately one of the simpler constructions, which makes it rather budget-friendly – even if bronze was the chosen material. Adding machining/tooling cost by designing a new bezel, and/or a new crown, would have a greater effect.
With all this in mind, I would highly recommend not changing many case components as the machining costs are rather high and would eat up a large amount of the remaining budget, thus limiting future choices for dial and hands."
