Bulgari Bulgari 102055— lug 18mm

The Bulgari Bulgari 102055 features a lug width of 18 mm. This dimension was calculated by Bulgari to maintain balanced proportions with the 41.50 mm case diameter. To measure the lug width accurately, use a digital calliper positioned perpendicularly between the two internal attachment pins. It is essential to avoid adding extra thickness, as oversized straps would visually unbalance the watch.

For the 102055, we recommend black or brown alligator leather, which amplifies the sophistication of the engraved bezel whilst maintaining visual continuity with the stainless steel case. Vegetable-tanned calf leather offers a patina that ages gracefully over time. Shell Cordovan is ideal for those seeking exceptional durability and a smooth, long-lasting surface. For warm climates, FKM rubber in grey or beige preserves practicality without compromising elegance.

The strap is replaced by removing the lateral spring bars that anchor the lugs to the case. Use a dedicated spring bar tool with a slot to grasp the pin, applying gentle pressure to extract it. Position the new strap by aligning its slots to the lateral attachments and reinsert the spring bar until you hear a clicking sound indicating secure locking. If unsure, consult a professional watchmaker to prevent damage to the case.

Yes, any strap with an 18 mm lug width is compatible with the 102055, regardless of the manufacturer. However, we recommend straps constructed from noble materials such as alligator, calf leather, or shell cordovan, which respect the jewel-watch vocation of the model. Fabric NATO straps are not recommended, as their weight and construction complexity visually overburden the strap.

Durability depends on the material and usage frequency. Alligator leather, if properly maintained, can last 5–8 years with daily wear. Vegetable-tanned calf leather offers similar longevity whilst developing a patina that enhances its appearance over time. Shell Cordovan is significantly more durable, potentially lasting 10+ years due to the natural structure of the leather. To extend strap lifespan, avoid prolonged exposure to extreme humidity and occasionally apply a conditioner specifically formulated for fine leathers.
