Condition:

This Omega Seamaster Professional 300M “Seaweed” Green is presented in excellent pre-owned condition and has been lightly used. The case and bracelet show minimal signs of wear, with only faint hairlines visible upon close inspection.

The watch has received a light, surface-level professional polish to refresh its appearance. This was strictly cosmetic in nature and did not alter the case geometry, edges, or factory finishing, which remain sharp and well-defined.

The green ceramic dial and bezel are pristine, with no marks, chips, or discoloration. The sapphire crystal is clear and free from scratches or chips, and the helium escape valve and crown operate smoothly.

The bracelet remains tight and well-fitting, all links are present, and the clasp functions properly with only light signs of use. The watch is running well and functioning as intended, with all features operating correctly.

Overall, this is a clean, well-maintained example that presents beautifully on the wrist and is ready to be enjoyed immediately.
