This Omega Speedmaster Moonwatch Professional Sedna™ gold Watch 310.60.42.50.01.001(Replica Omega Speedmaster Moonwatch), it uses the unique Sedna 18K gold developed by Omega. The first appearance of this material was at the 2013 Basel Watch Fair. Omega announced the first A watch made of Sedna 18K gold, the constellation series Sedna. Sedna gold is a kind of 18K rose gold with a blazing hue. It is more rosy than ordinary 18K rose gold because it is made of three metal elements: gold, copper and palladium. This material first has a minimum gold content of 75%, and then adds an appropriate proportion of copper to ensure its rose red color, and secondly, the incorporation of palladium ensures its eternal and lasting color. The name of this new alloy is also derived from the outer Neptune celestial body called Sedna by astronomers. The Sedna asteroid is considered to be one of the reddest celestial bodies in the solar system. The successful development and application of Sedna gold also allowed Omega to gradually replace the ordinary 18K rose gold with this material, and then use it in other series of flagship watches.
The watch uses Sedna 18K gold to make an asymmetrical case. The diameter of the case is 42 mm. The case has been modified with a brushed effect. The edges of the case are polished by Omega. There are two chronograph buttons on the other side of the case and a winding crown. The size of the crown has been increased compared to the old model. The anti-slip pit pattern on the whole body is used to facilitate the wearer to better grasp and adjust the winding. The top is also Engraved with the Omega brand logo. The timing button is also very comfortable to operate, and the flat-top shape will not make it squeaky.
In order to better restore the classic design of the prototype watch, on the black anodized aluminum bezel of the watch, the tachymeter scale is decorated with the famous Dot over 90 mark, that is, the 90 scale dot is located above the number. The black stepped dial also follows the design of historical watches, and we can see the obvious step effect through the close focus map above. There are three sub-discs on the dial, namely the 30-minute chronograph at 3 o’clock, the 12-hour chronograph at 6 o’clock, and the small seconds at 9 o’clock, the central hour hand, and the arched minute and chronograph seconds hand. The tail of the second hand has also changed from the old flat head to the pointed one. There is also a small change on the dial to adjust the minute scale to adapt to the vibration frequency of the new movement.
Sedna 18K gold hands and hour markers are coated with luminous paint to ensure that the watch can be read clearly even in a dimly lit environment. The above picture shows the real luminous effect of the watch. The watch adopts a back-through design, and under the sapphire transparent back cover is a new movement, which is also the most significant upgrade of the watch. Omega upgraded it from the old 1861 movement to the 3861 Master Chronometer movement, which is equipped with a non-card-spring balance wheel with a silicon balance spring and a coaxial escapement. The movement is rhodium-plated and the plywood is also decorated with vertical Côtes de Genève. Under the condition that the size of the new movement is exactly the same as that of the old movement, the power reserve, chronograph performance and anti-magnetic performance have been greatly improved. The daily time error has been increased from -1/+11 seconds to 0/+5 seconds. The antimagnetic performance is as high as 15,000 Gauss, the power reserve is 50 hours, and the stop-second function is added. The vibration frequency of the movement of the 3861 Zhizhen Observatory is 21,600 vibrations per hour, that is, the second hand moves 3 times a second, and this is the reason for changing the minute scale on the dial.Omega Watches Replica
