Breitling Navitimer 1 B01 Chronograph 43 – Automatic Pilot’s Watch with Black Dial

Featuring a 43 mm polished stainless steel case, crisp black dial, and robust black leather strap, this automatic chronograph combines heritage aviation design with modern watchmaking precision. Protected by a scratch-resistant sapphire crystal and rated to 3 ATM (30 m), it’s both elegant and durable—perfect for the skies or everyday wear.
