The Collection

Pieces currently in the family vault

A rotating selection of high-end references. Reserve a piece to hold it in your name, or inquire and we'll walk you through condition, service history and provenance — person to person. Pricing is by inquiry only — with gold and precious-metal markets moving daily, we quote each piece current at the time you ask rather than list a price that’s out of date tomorrow.

The “Bruce Wayne,” by day and after dark

The GMT-Master II reference 126710GRNR pairs a black lacquer dial with a two-tone grey and black Cerachrom bezel and a green GMT hand — understated in daylight, unmistakable at night, when the Chromalight display takes over.

In daylightThe physical piece
Rolex GMT-Master II Bruce Wayne luminous effect — Chromalight hour markers, hands and GMT triangle glowing blue in low light
After darkChromalight lume

Rolex's Chromalight material emits a long-lasting blue glow, charged by light during the day. On the Bruce Wayne every hour marker lights up — circles, batons and the inverted triangle at 12 — along with the hands and the GMT hand's arrow tip, so home time and the second time zone stay readable in the dark without a second glance.

The Houses

Three names. No substitutes.

We deal in the references that hold their value and their mystique — the crown, the winged B, and the house that went to the Moon.

Geneva · Est. 1905

Rolex

Submariner, Daytona, GMT-Master II, Datejust. The most requested, the most counterfeited — which is exactly why every Rolex we sell is verified down to the movement.

View Rolex pieces →
Grenchen · Est. 1884

Breitling

Navitimer, Chronomat, Superocean. Instrument-grade chronographs built for pilots and worn by people who appreciate serious engineering on the wrist.

View Breitling pieces →
Biel/Bienne · Est. 1848

Omega

Speedmaster and Seamaster. The first watch on the Moon and the diver on half the wrists in the room — Master Chronometer precision, quoted fairly on inquiry.

Our Story

Every family has a watch guy. Ours is the real one.

La Cosa Nostra Watch Company started the way the best collections do — one man, one coat, and more watches than any reasonable person needs. What began as a personal obsession with Rolex, Breitling and Omega became a business built on a simple code: know every piece, vouch for every piece, and treat every buyer like they're joining the family.

The name is a nod to that code. Around here, a handshake still means something, a reputation is worth more than a quick sale, and when we say a watch is right, you can take it to the bank. No games, no stories that change, no pressure — just serious timepieces and straight answers.

LoyaltyBuyers come back because they're treated like family, not transactions.
RespectFor the craft, for the brands, and for your money.
DiscretionRemote consultations, quiet deals, unbranded insured shipping.
Current, honest pricingQuoted on inquiry so every price reflects today’s gold market — never a stale list price.
How It Works

Three steps. No surprises.

STEP — 01

Inquire or Reserve

Found your piece? Reserve it to hold it in your name while we talk, or inquire first for condition photos, service history and provenance details.

STEP — 02

Verify Together

We walk you through the watch remotely — movement, serials, paperwork, timing results — over a video call, with detailed photos and video sent your way.

STEP — 03

Complete & Ship

Settle up securely, and the watch travels fully insured and tracked in unbranded packaging, straight to your door.

Sourcing

Hunting a specific reference, year or dial? Tell us the watch and we'll put the word out through our network. Most requests land within a few weeks.

Authentication

Buying elsewhere and want a second set of eyes? We verify movements, serials and paperwork on Rolex, Breitling and Omega pieces.

Sell or Trade

Ready to move a piece on? We buy outright and take trades toward anything in the collection. Fair offers, fast decisions, no lowball theater.
