Comparison between a stamped buckle and a CNC machined one

Can you spot the differences?
Stamped
CNC machined buckle
Little more into details:
For most of our straps we are offering CNC machined buckles.
- Rounded edges on the stamped buckles are typical, it lets the buckle look "cheap" in our eyes. The CNC machined buckle have crisp edges which let them look more premium.
- While rounded edges are good against sharp edges, a CNC machined buckle could sometimes feel as sharp.
- The precision of the stamped buckle is lower as they are produced through heavy pressing. The CNC machined buckles are done within tolerance of few millimeter.
- Stamped buckle are usually made out of 304L stainless steel, while for CNC machined buckles, we use 316L stainless steel.
- Price for a stamped buckle is about USD 0.42, a machined buckle costs more than 10x and for us the average cost is about USD 7.00 per piece (including the luminous)
What do you think? Which way do you prefer?
Titanium case backs

Early rendering stage of an upcoming project we are working on. The renders are not final. There will be some changes like the bezel insert engraving style, hands. Additional dials. 41 mm diameter, 46 mm lug to lug, 12.50 mm height, powered by Sellita Elab Grade SW200-1 or Soprod Newton (could not decide yet). Lugs are 20 mm. Stainless Steel 316L with experimental hardening which gives the steel a hardness of 1800-3000 HV, we will provide a test report to proof our claims, just like with the lume, we like to verify what we promise and not just blind-trust our suppliers! Genuine Swiss Made Lumicast indices and chapter ring with highest possbile Grade of lume and some even have a lumicast dial (in the works). Hands are polished with middle chamfer. Box sapphire or maybe double domed (not decided yet). Exhibition case back. Parts are made in Switzerland and China with final assembly and QC in Switzerland with our watchmaker in La Chaux-de-Fonds. We ship from our Swiss Office worldwide. This way we can offer it at an affordable price. we are aiming at $649 including shipping. Each color will be limited to 50 pieces. How do you like it? The project is not named yet ^^
