Omega The newly upgraded Seamaster 300M

Original price was: $550.Current price is: $400.

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.

Movement information

See what powers the watch

Listed movement: Automatic mechanical.

Before shipping, ask for a clear caseback photo, a short running video and the timing-machine result. Decoration, rotor shape and bridge layout can vary by batch, so the QC image of the individual watch is the controlling reference.

  • Movement and function check
  • Time/date/chronograph test where applicable
  • Timing rate and amplitude photo when available
  • Rotor noise and winding feel checked

FAQ & verification

Questions to ask before paying

Is this sold as an authentic brand-manufactured watch?

No unless the listing explicitly provides verifiable provenance and authorised documentation. Store grade labels describe configurations; they are not authentication certificates.

How can I verify what I will receive?

Match the QC photos to the order reference. Request a dated video showing the dial, caseback, clasp, serial/marking areas, movement where accessible, and every function. Save the approved QC record.

Can a photo prove authenticity?

No. Photos can help confirm appearance and the shipped item, but authentication requires provenance and qualified physical inspection. Never rely on a logo, serial number or packaging alone.

What should I check in the timing result?

Confirm that the displayed watch is running, then review rate, amplitude and beat error. Results are a snapshot, not a lifetime guarantee, and can change with position, temperature and transport.

Is the watch safe for swimming?

Only if the individual watch has passed an appropriate pressure test and the result is documented. Otherwise treat it as splash resistant and keep it away from showers, pools and seawater.

When will the order ship?

QC in 2–4 business days; delivery commonly 7–14 business days after approval. Tracking is issued after QC approval and dispatch.
