🟡 1958 Omega Seamaster Chronograph Cal. 321 – 18ct Solid Gold – Full Set (Box & Papers)

£8,500 | Investment-Grade Vintage | One of the Rarest Configurations You’ll See

This is, quite simply, one of the rarest vintage Omegas we’ve handled in a long time.

A 1958 Omega Seamaster Chronograph powered by the legendary Calibre 321, presented here in solid 18ct yellow gold and offered as a true full set with original box and original papers dated 1952. The serial number reconciles perfectly with the paperwork – there is no question on originality or period correctness. Watches like this do not surface often, and when they do, they are usually already locked away in collections.

Most examples you’ll see in the market are steel, gold-plated, or 14ct.

An 18ct solid gold Cal. 321 Seamaster chronograph with box and papers is on another level entirely.

📈 Why This Is a Serious Investment Piece

Calibre 321 – the same movement lineage as early Speedmasters and one of the most sought-after chronograph movements ever made.

Solid 18ct gold case – far rarer than steel, gold-plated or 14ct examples.

Full set with matching papers – exceptionally rare on 1950s chronographs.

Correct period details – including the unsigned crown, confirmed as original.

Original creamy patina dial – untouched, honest ageing that collectors actively pay a premium for.

Timeless proportions – 35mm vintage cases are highly wearable and increasingly desirable.

This isn’t a hype watch. This is the sort of piece that quietly appreciates while sitting in a serious collection. The supply is fixed, and examples with this level of completeness are getting scarcer by the year.
