Speake-Marin Dong
Speake-Marin unveil the Dong Son, a specially-commissioned, limited edition featuring an 18k red gold dial with etched motif inspired by ancient Dong Son bronze drums
The Dong Son – inspired by a Vietnamese cultural treasure
The Dong Son by Speake-Marin is a commissioned, limited-edition timepiece featuring a red gold dial stunningly etched away to leave a fascinating motif inspired by the prehistoric bronze drums of the Dong Son culture in the Red River Delta of Vietnam.
The intricately detailed dial is complemented by the drum-like Speake-Marin Piccadilly case in 18k red gold, further evoking the beauty of the ancient Dong Son drums.
In addition to the signature Piccadilly case, the Dong Son possesses other quintessential Speake-Marin qualities including characteristic pleated crown, signature Foundation hand, mystery winding rotor and features the new, automatic-winding Eros 1 movement with five-day power reserve.
Peter Speake-Marin says: “It has been a pleasure to explore and showcase the ancient Dong Son culture and one of its prized artefacts through creating the Speake-Marin Dong Son timepiece.”
The Dong Son bronze drum culture
Dong Son drums are bronze drums crafted by the Dong Son culture in the Red River Delta of northern Vietnam between about 600 BC and the third century AD. The Dong Son people were highly-skilled bronze casters and their drums are considered to represent an artistic level that few cultures of the time could match. Weighing up to 100kg, some drums would have required the smelting of between one and seven tons of copper ore. Since the late 17th century, more than 200 such drums have been discovered from eastern Indonesia to Vietnam and parts of southern China.
Drum from Sông Đà, Vietnam. Dong Son II culture. Mid-1st millennium BCE. Bronze.
It is generally thought that the Dong Son drums were used as musical instruments in festivals, in prayers for rain and for good harvest, in rituals such as weddings and funerals, and for rallying men for war. The sides and top surface of the drums were usually decorated with geometric patterns and realistically inscribed scenes depicting daily life, for example war, animals and boats.
The unique dial of the Dong Son
These traditional patterns and iconography provide the inspiration for the highly-intricate dial motif of the Speake-Marin Dong Son. In fact, the Dong Son dial motif takes its cues from some of the most revered Dong Son drum creations, including the Hoàng Ha drum, Co Loa drum and the most important of all due to its well-preserved nature and intricate decoration, the famous Ngoc Lu drum.
The top surfaces of these drums are adorned with a central starburst and concentric circles within which are repetitive images of armed warriors and flying egrets as well as geometric hatching.
The dial motif of the Speake-Marin Dong Son follows a similar pattern to these historical masterpieces, with an outer ring of graceful egrets complemented by an inner ring featuring plumed warriors holding their weapons between the 12 points of the eye-catching starburst. These 12 points also form a neat horological reference for the central, sculptured signature Speake-Marin ‘Foundation’ hands indicating hours, minutes and seconds.
Intricate etching
It is not just the iconography of the Dong Son drum motif that gives the Dong Son dial its vitality, but also the spectacular precision of the etching in the 1.0mm 18k gold dial.
“The precision of the etching to create the Dong Son dial motif was only made possible thanks to an extremely innovative chemical etching process,” says Peter Speake-Marin. “Such an astonishing level of detail couldn’t have been achieved by human hand.”
The etched areas are 0.3mm deep and boast a matte finishing which impresses when applied to the natural red gold and when the dial is treated with an ‘all white’ or ‘all blue’ process that provides a breath-taking contrast with the circular-grained, red gold motif.
Signature Speake-Marin Piccadilly case
The Dong Son features an 18k red gold Piccadilly case with soldered lugs, bearing all the hallmarks of Speake-Marin’s meticulous quest to create classical masterpieces that endure – just like the Dong Son drums themselves.
At first glance the three-piece case appears similar to the original Piccadilly, but on closer inspection it can be seen that this one is much slimmer – just 12mm in height and 38mm in diameter – an elegant design made possible by the new Eros 1 calibre.
Display-back and Eros 1 movement
The Eros 1 calibre is an automatic winding movement and features a long, five-day power reserve and the signature Speake-Marin ‘mystery’ winding rotor. The large-diameter, circular-grained movement dominates the view through the display-back and provides a technical backdrop for the beautifully finished rotor.
