I made a passing comment a couple months ago (during the brief snafu when Sinn attempted to not disclose their movement manufacturers) that there was more motivation than ever for Sinn to design and produce an in-house movement.
Reports keep coming from customers dissatisfied with the Sellita movements in their watches. It's reasonable to believe that Sellita is struggling to ramp up production and meet demand as Swatch continues to tighten their grip on ETA and Valjoux movements, and that eventually they'll sort out the issues and start putting out reliable and accurate movements at a large scale. I also believe that Sinn puts more effort into inspecting and regulating the movements they buy than any other brand at their price point.
Nevertheless, as some owners here can attest, a few lemons have managed to sneak through. For a brand that prides itself on functionality above all else, even one mechanical issue is too many. Cosmetic flaws, squeaky bracelets-- fine. But professionals rely on these watches to function. The prospect of repair service being covered under warranty is little consolation if your watch fails when you need it most.
All this is to say that to secure the future of their brand, Sinn should seriously be considering an in-house movement. The cost is enormous and the risk is huge. When a Sellita movement fails, we can blame Sellita. When an in-house movement fails there's nothing to hide behind! But, Sinn has unique advantages compared to other potential movement manufacturers. They already have a large amount of knowledge, technical skill, and machinery in place for their Diapal and SZ-01 modifications. They would hardly be starting from scratch.
So, a few questions for the members here:
1. Do you think Sinn should go in-house?
2. Would you be wiling to pay the higher costs that would inevitably be associated with in-house?
3. Is there a potential here for an intermediary step, where Sinn continues to use Sellita but modifies ALL of their mechanical movements to ensure reliability? (E.G. Diapal across the line).
4. Is there a potential here for more quartz calibers? When properly constructed, mechanical watches are robust enough for professional use (as demonstrated by the 756 on the wrist of a crash test dummy!). But quartz undoubtedly has the edge for shear functionality. I think many of Sinn's customers feel no romance for mechanical and would gladly take a quartz option.
5. Is there a potential for Sinn to start using Japanese movements, and would you be willing to purchase them? Seiko, and more recently Miyota, certainly make robust movements. Even the lowly 7S26, the Honda Civic of mechanical movements, is famous for going up to a decade without servicing. On the higher end of what Seiko offers, surely Sinn could find a movement that meets or exceeds their requirements.
Lots to think about. I'd love to hear your thoughts!
