Omega Speedmaster Professional Moonwatch Watch 310.30.42.50.01.001(Replica Omega Speedmaster), the watch is made of stainless steel asymmetrical case, the diameter of the watch is 42 mm, the case is modified with a brushed effect, and the edges and corners of the case are polished by Omega . There are two chronograph buttons on the other side of the case and a winding crown. Compared with the old model, the size of the crown has been increased. The anti-slip pit pattern on the whole body is used to facilitate the wearer to better grasp and adjust the winding. Engraved with the Omega brand logo.

 The watch uses Hesalite plexiglass as the table mirror, which is what we often call the acrylic material. This material is used to better restore the prototype watch. In addition, there are many small details to restore the classic design, such as the anode. On the alumina bezel, 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 the historical watch. 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 and the 6 o'clock position. The 12-hour chronograph dial, the small seconds at 9 o'clock, the central hour hand, the arched minute hand and the chronograph second hand, the tail of the central seconds hand has also changed from the old flat head to the pointed style. There is also a small change on the dial to adjust the minute scale in order to adapt to the vibration frequency of the new movement. I would like to say here that the brand logo at 12 o'clock on the plate, the sapphire mirror uses a three-dimensional metal label, and this acrylic version still uses the printing style.

The hands and hour markers of the watch are coated with green luminous paint. The picture above shows the real shot effect of luminous light, which ensures the readability of the watch in dimly lit conditions at night. This acrylic table mirror style uses a dense bottom design, embossed seahorse emblem pattern and other information on the bottom cover. The new movement mounted under the back cover, OMEGA upgraded it from the old 1861 movement to the 3861 Master Chronometer movement. In the case of exactly the same size as the old movement, this new manual winding movement The power reserve, timing 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 anti-magnetic performance is as high as 15,000 Gauss. The power reserve is 50 hours. Stop seconds function. The vibration frequency of the movement of the 3861 Zhizhen Observatory is 21,600 times per hour, which means that the second hand on the dial moves 3 times a second. Replica Omega Watches
