Omega Speedmaster Triple Calendar 3521.30.00 – Steel White Dial

Trade In
Details

The Speedmaster that does more in a lighter tone

This Speedmaster Triple Calendar carries the same familiar case shape and overall feel, but the matte white dial shifts the mood completely. The layout is the same, the information is the same, yet the watch feels brighter and more open on the wrist. At 39mm, it remains easy to wear and unmistakably Speedmaster.

Why this configuration matters

The triple calendar layout is what defines this reference. Day, date, and month are worked into the dial in a way that keeps everything balanced. On a matte white backdrop, the display feels clear and intentional rather than dense. This reference sits comfortably between a standard chronograph and something more involved. 

What you need to know before wearing it

Condition is very good throughout. The case, bezel, and bracelet are all in very good shape with no noticeable major flaws. The dial and crystal are clean and well preserved. The movement is running properly and all functions operate as intended. The watch comes with its original card.

Why this watch still works

This is a Speedmaster for someone who wants added functionality without added noise. The matte white dial makes it versatile and easy to pair with anything. It works as a daily chronograph, a more distinctive alternative to the standard Speedmaster, or a thoughtful piece from Omega’s 1990s lineup. Familiar in form, different in tone, and quietly compelling on the wrist.

 

Bracelet extension, cutting, or sizing is available upon request through our professional in-house jewelers.

History

In 1957, Omega released the Speedmaster as a racing chronograph. Eight years later, NASA put it through a battery of extreme tests — temperature, humidity, vacuum, shock, vibration, acceleration — and in 1965 certified it as the official watch for all manned space missions.

On July 20, 1969, Buzz Aldrin wore his Speedmaster on the surface of the Moon. No other watch has been to the Moon. That fact has never stopped mattering to anyone who cares about watches.

The Speedmaster's production history across our inventory is rich: the manual-wind Professional (ref 145.022 from 1969 itself), the Reduced automatic (3510.5, 3511.5, 3511.8 with date), the Triple Calendar series (3521, 3523.3), the Michael Schumacher limited editions (3810.12, 3518.5), and the AC Milan and Schumacher World Champion 2000 editions. Each variant was built on the same essential chassis — the 39mm steel case, the tachymeter bezel — and each one lands somewhere on the continuum between racing instrument and artifact of human achievement.


What Our Clients Say About Us

I knew I was gonna like Danny, based on his name, but nothing could’ve prepared me for how great of an experience this was. He had the most beautiful 70s Seamaster Cosmic on his website and I was set to be married 2 days later - I arranged to buy it but before leaving we both realized it needed to be serviced. I panicked, because I was literally buying this for my wedding, and Danny being the legend he is, loaned me a nearly identical Seamaster to make sure I could get through the event Never have I had someone go so above and beyond for me, especially while purchasing one of the lesser priced items in their inventory. He serviced my watch and exchanged it with me after the wedding on a super fast turnaround timeline. I would sincerely recommend you visit this guy, you will not be disappointed Edit: adding a pic of the loaner (two tone) and the owner (crosshair)

Great service and shop. Danny and his team were incredibly accommodating, professional, and kind. Great selection of vintage watches. Their store is the hidden gem in the diamond district.

This was my first real luxury watch purchase, a Rolex 15200 Date 34mm, I own Tissots and a Laco, but those are entry level luxury watches. I found Danny’s Vintage Watches online, and had great feedback both on Google, Chrono24 and the Reddit watch community. So decided to give him a shot as buying online can be a crap shoot. Ordered Monday night, was at my doorstep Friday morning. Despite the watch being over 30 years old, serial number says it’s from 91, the watch looked new. Didn’t come with box or papers, and was shipped in a plastic sleeve wrapped in bubble wrap. Danny was always available to answer questions. I’ll be buying from Danny again for the next purchase…saw a couple of Speedmasters on his site I liked….
