A Statement Piece for your Collection:
This stunning piece of wearable art is for the bold individual who isn’t afraid to stand out and yearns for a watch that commands attention. The skeletonized dial, with its intricate bridges and oscillating rotor, is a mesmerizing display of horological artistry. The blue chronograph counters and the blue-tinged El Primero 21 movement create a stunning contrast against the grey titanium case. With its 1/100th of a second chronograph and 50-hour power reserve, this watch is not only a feast for the eyes but also a powerhouse of performance.

The Arieli Collection Difference
Experience exceptional service with every purchase. Your watch deserves the utmost care, and I’m dedicated to delivering nothing less. Each watch undergoes a cleaning and sanitization process before being expertly packed and shipped overnight. For your peace of mind, I record the entire packing process on video. To protect your investment, I provide a 12-month warranty for any timepiece that no longer has an active manufacturer’s warranty (any exclusions will be noted in the listing). Even after both warranties expire, I can offer access to our skilled watchmakers at competitive prices. For eBay purchases, the watch is sent to their Authenticator for authentication before being shipped directly to you by eBay.
