Omega Seamaster Collection: Top-of-the-Line Model with Sapphire Crystal Glass

Pros

• · Catalog states a 42mm case, 316 stainless steel, sapphire crystal front and back, exhibition caseback, unidirectional rotating bezel, screw-down crown, folding steel clasp, lume, and a helium escape valve.
• · Owner reports on the green Seamaster 300 describe the dial and bezel as dark forest green in normal light, brighter emerald in direct sun, and near-black at night — a genuine colour shift rather than a flat finish.
• · Owner reports on the green Seamaster 300 line describe accurate, consistent timekeeping over weeks of daily wear.

Cons

• · The catalog text labels the build a high-end replica, not brand-authorized stock, so Omega warranty and service channels are not part of the purchase.
• · No independent buyer report covers this specific SKU; the owner claims above describe the genuine line, not the watch you would receive.
• · Owner reports on the genuine steel-bracelet Seamaster 300 describe a top-heavy feel and pulling on the wrist, with some owners switching to rubber.

Fit notes

42mm case. Genuine-line owner guidance says the green Seamaster Diver 300M at 42mm gives a large, prominent wrist presence rather than a subtle fit. This listing gives no lug-to-lug or thickness figure, so ask the agent for those if wrist fit is decisive.

Buy if

You want the Seamaster 300M look — 42mm case, green dial and bezel, rotating bezel, exhibition caseback — and you are buying it as a replica, ready to check caseback engraving, movement finish, and clasp details with the agent before paying.

Skip if

You need brand-authorized provenance, an Omega warranty, or stamped papers. Or you want a light, low-profile watch: 42mm in this line reads large, and owner reports on the genuine steel-bracelet Seamaster 300 describe a top-heavy feel.
