Introduced in the 1970s, the Baume & Mercier Tronosonic 5109 is a distinguished timepiece powered by the innovative ESA tuning fork movement, known for its ultra-smooth sweeping seconds hand and signature electronic hum. This particular example features a 35mm stainless steel case and a sleek black sunburst dial with applied indices and a framed day-date complication at 3 o'clock.What sets this watch apart is the Arabic print on the dial referencing Sheikh Hamdan Bin Mohammed Bin Khalifa Al Nahyan, a key figure in the formation and progress of the United Arab Emirates. The late Sheikh held pivotal governmental roles, serving as Minister of Public Works and Housing as well as Deputy Prime Minister. He was instrumental in the development of national infrastructure during the UAE’s early years.Watches like this were often commissioned as diplomatic or honorary gifts. This particular piece, marked with "Abu Dhabi," was likely presented as such. It combines the historical significance of a statesman’s legacy with Baume & Mercier’s commitment to horological innovation. The watch is accompanied by its original box and remains a collector’s piece reflecting both fine craftsmanship and regional history.
