The Bulgari Octo Finissimo Skeleton 8 Days (Ref. 104121), with its ultra-thin skeleton design and black DLC titanium case, perfectly embodies the fusion of haute horlogerie and modern Italian style. This watch is not only a technical breakthrough, but also a dazzling visual design, making it another masterpiece in Bulgari’s ultra-thin watch collection.
1. Design and Materials
- The case is crafted from grade 5 titanium with a black DLC coating, creating a lightweight and contemporary look. Measuring 40mm in diameter and just 5.95mm thick, it is both slim and comfortable.
- The octagonal case features sharp lines and 58 facets, creating a striking geometric contrast with the round bezel.
- The brushed surface creates a delicate touch, and the 18K rose gold crown with a black ceramic inlay exudes elegance and sophistication. – The skeletonized movement bridges feature a matte dark gray hue and a black PVD coating, creating a technical look with a distinctly modern aesthetic.

2. Movement Performance
- Equipped with the in-house BVL 199SK manual-winding movement, it is only 2.50 mm thick and offers a remarkable 192-hour (8-day) power reserve.
- The small seconds dial is located between 7 and 8 o’clock, and the power reserve indicator is displayed above it on a graduated scale for easy readability.
- The movement architecture can be admired through the transparent sapphire crystal caseback, and the double-support balance bridge enhances shock resistance.

3. Practical Performance
- Water-resistant to 3 bar (approximately 30 meters), it is suitable for occasional splashes in daily life, but not suitable for swimming.
- It comes with a flexible black rubber strap and a black DLC titanium pin buckle, matching the watch’s sporty and modern aesthetic. Its lightweight feel and bold visual design make it instantly recognizable on the wrist without feeling bulky.
