Omega watches are renowned for their quality, precision, and – often overlooked – their exceptional finishing. The meticulous attention to detail, visible even in the subtle nuances of a brushed flank, speaks volumes about the brand's commitment to craftsmanship. This article will explore the intricacies of achieving that signature Omega finish, focusing specifically on the challenges and techniques involved in brushing the side flanks, particularly those with crown guards. We'll also compare Omega's finishing approach to other prestigious brands like A. Lange & Söhne (ALS) and Girard-Perregaux (GP), highlighting the subtle yet significant differences that define each manufacturer's aesthetic.
Advice on Putting a Brushed Finish on Side Flanks with Crown Guards
The side flanks of a watch case, especially those incorporating crown guards, present a significant challenge for finishing. The complex curves and often tight spaces necessitate specialized tools and techniques to achieve a consistent, high-quality brushed finish. As mentioned, a benchtop polishing lathe with a 4-inch Bergeon 6723-240-LP wheel is a common tool for achieving a brushed finish. However, the size of this wheel presents a limitation, particularly when dealing with intricate areas like crown guards. The large diameter makes it difficult to reach into tight corners and maintain a uniform brushing direction.
The solution often involves a combination of techniques. For the larger, more accessible areas of the flank, the 4-inch wheel is ideal. It provides a consistent, even brushing action, producing a uniform texture. However, for the crown guards and other tight spots, smaller, more specialized wheels and tools are required. These can include:
* Smaller diameter brushing wheels: Bergeon offers a range of smaller diameter wheels specifically designed for intricate detailing. These allow for more precise control and access to challenging areas.
* Hand brushing tools: For the most delicate and intricate areas, hand brushing with fine grit abrasives might be necessary. This requires a high level of skill and precision to ensure a consistent finish that matches the rest of the case.
* Abrasive papers/tapes: These can be used for initial shaping and smoothing of the surface before the final brushing. Different grits can be used to progressively refine the surface texture.
* Polishing compounds: After brushing, fine polishing compounds can be used to subtly refine the brushed finish and remove any minor imperfections.
The key to success lies in maintaining a consistent brushing direction and pressure. Changing the angle or pressure can lead to inconsistencies in the finish, resulting in visible streaks or variations in texture. Practice and patience are essential to mastering this technique. Always start with a coarser grit and progressively move to finer grits to achieve the desired level of refinement. Regular cleaning of the tools and the work piece is also crucial to prevent contamination and ensure a clean, even finish.
GO vs ALS Finishing
Comparing Omega's finishing to that of other high-end brands provides valuable insight into the nuances of watchmaking aesthetics. Girard-Perregaux (GP) and A. Lange & Söhne (ALS) represent two different approaches to finishing.
