Frequently asked questions

What is the lug width of the Bulgari Octo 102705?

The lug width of the Bulgari Octo 102705 is 24 millimetres. This measurement is specific to the model and derived from the octagonal geometry of the case. To verify it correctly, measure the distance between the two internal lugs of the case, excluding the lateral shoulders. It is essential to respect this measurement to maintain the aesthetic proportions of the watch.

Which strap is recommended for the Bulgari Octo 102705?

For the stainless steel Bulgari Octo 102705, the ideal strap is black alligator with yellow gold stitching for versions featuring a silver sunburst dial. If you prefer a more classical approach, chocolate brown alligator or shell cordovan in burgundy tones offer a patina that improves over time. For daily wear, smooth black calf leather or a grey-blue NATO represent practical choices without aesthetic compromise.

How do I change the strap on my Bulgari Octo 102705?

To change the strap on your Bulgari Octo 102705, use a dedicated tool (spring bar tool) to remove the springs from the lugs. Position the tool under the spring, gently pushing inward to release it, then withdraw the old strap. Insert the new strap aligning it perfectly with the lug holes, ensuring the spring is completely seated. Verify that the strap is firmly secured before wearing the watch.

Are compatible aftermarket straps available for the 102705?

Yes, Milano Straps offers a comprehensive selection of 24mm straps compatible with the Bulgari Octo 102705, available online ready for shipment.

How long does a leather strap last on the Bulgari Octo 102705?

The lifespan of a leather strap depends on the material and usage. Quality alligator or shell cordovan can last 3-5 years with daily wear and proper maintenance, developing a desirable patina. Smooth calf leather has a similar lifespan, generally 2-4 years before showing signs of wear. The natural ageing of leather is not a defect but rather a characteristic that enriches the strap over time.
