The newly upgraded Seamaster 300M

The newly upgraded Seamaster 300m has arrived. Upholding its reputation for practicality while meticulously refining aesthetic details and incorporating an imported integrated movement, this model embodies a philosophy of continuous improvement—propelling the entire Seamaster series to new heights with this latest movement.
[Upgrade 1] The color of the bezel insert now perfectly matches the dial; the recessed luminous dot is synchronized with the original, as is the luminescence color.
[Upgrade 2] The automatic rotor has been modified to mirror the original 8800 movement; it combines the proven durability of the imported 9015 movement with a visual appearance that is strikingly close to the genuine article.
[Upgrade 3] Upgraded to a domed, scratch-resistant sapphire crystal; from now on, all models in the series feature sapphire crystal.
[Upgrade 4] Manufactured using CNC molds based on the original, it perfectly replicates the case shape and bracelet curvature, achieving a level of visual fidelity that is virtually indistinguishable from the genuine watch.
