Swiss Omega Seamaster 300M series purchased the original 1-1 model to build.
1.The brand new seahorse 300 meters is upgraded to be consistent with the genuine product. Full ceramic dial size: 42MM
2.The brand new seahorse 300 meters is upgraded to the same perspective bottom as the genuine product.
 The scales and characters on the upgraded ceramic ring adopt the “white enamel” process to prevent yellowing and keep the pure white and shiny fonts brighter for a long time.
4.The upgraded case is 42mm, the 11 o’clock exhaust valve is changed to a conical shape, and the bottom line of the new 300-meter case is not so big.
5.The headband of the upgraded watchband can be bent more closely, and the buckle can be adjusted in length. The customized version of the 8800 movement is the same as the original version. The calendar has a quick jump function. The strap makes the wrists bloom with different colors (while stocks last).
The version and the genuine product have precious metal marks on the outer ring at 12 o’clock: AU750, dog head mark, balance scale, and European logo. You can see if there is this mark to distinguish the /market version.
