Omega Seamaster 300 Heritage Models Co-Axial Master Chronometer 41mm Yellow Gold on Leather Strap, 234.63.41.21.99.001

OMEGA first introduced the Seamaster 300 in 1957 as a watch especially for divers. On this contemporary model, the legendary design has been transformed for luxury style. The 41 mm case has been made from 18K yellow gold and features a green ceramic bezel with an OMEGA Ceragold diving scale. Most captivating of all is the watch's deep green dial, which is made from the precious stone malachite. It includes 18K yellow gold hands that are filled with "vintage" Super-LumiNova. Presented on green leather strap, the watch is driven by the OMEGA Master Chronometer Calibre 8913, certified at the industry's highest standard by the Swiss Federal Institute of Metrology (METAS).

📦 Shipping Logistics Process

To ensure the highest level of security for high-value shipments, we operate through a structured and insured logistics process.

As outlined in our listings, all orders are first consolidated through a specialized external logistics partner. This partner securely collects and groups multiple shipments before transferring them to DHL for final delivery to the customer. Handover points may vary depending on routing.

This procedure is mandatory for insurance and risk management purposes. High-value items cannot be handed directly in bulk to standard courier pickup without appropriate secured handling, as this would not be covered by insurance policies.

As a result, while your order may be prepared and assigned a tracking number promptly, the parcel may take several working days before it is physically handed over to DHL and becomes active in their tracking system.

Estimated handling and dispatch timeframe: 5–7 business days.

During this period:

- Tracking may not show updates immediately

- The shipment is already in a secured logistics flow

- Updates will appear once DHL officially scans the parcel into their network

This process ensures maximum protection of the goods and is standard practice for high-value watch logistics.


For watches specifically indicated as unworn and complete with their original manufacturer warranty, we confirm that they are supplied with a fully valid manufacturer warranty, activated by official brand-authorized dealers.

Where applicable, this includes the extended warranty period (up to 8 years) and is valid worldwide for all brands (e.g. Rolex, IWC, Panerai, Zenith, etc.). In practical terms, this means the watch is fully covered by the brand, exactly as if purchased at retail, for service and warranty purposes.

As for personal online registration under the brand’s website or app, in most cases this is possible. However, in some situations—typically when a watch was originally registered by its first owner at the time of purchase—the brand may require the cooperation of the previously registered holder to change the account details. This does not affect the validity of the warranty in any way. Even in these rare cases, the warranty remains active, official, and fully enforceable worldwide; the only potential limitation is the ability to re-register the watch under a new personal email address. We explain this to ensure the highest level of transparency and peace of mind for our clients.
