The blue-dial Zenith El Primero 410 Triple Calendar and Moonphase was a 2015 limited edition combining an automatic high-beat chronograph with day, date, month and moonphase indications. Monochrome-Watches reported production of 1,975 pieces and an approximate launch price of €8,500. The “cool cufflinks” were a separate accessory: handmade solid-silver El Primero cufflinks by New York-based artist Baz Persaud, reported from $395 at the time. Neither figure establishes a current price or availability.
What the blue El Primero 410 is
Zenith’s 2015 blue version brought a triple calendar and moonphase to the El Primero 410 automatic chronograph. The movement combines chronograph counters for 30 minutes and 12 hours with day, date, month and moonphase displays. The 2015 Monochrome-Watches article lists 390 components, 31 jewels, a 50-hour power reserve and a frequency of 36,000 vibrations per hour (5 Hz). These are specifications reported for that edition, not for every watch called El Primero 410.
The calendar is a full calendar, not an annual or perpetual calendar. It displays the day, date and month but does not automatically account for months of different lengths, so the date requires adjustment as needed.
How the calendar and moonphase are arranged
- Day: at 10 o’clock.
- Month: at 2 o’clock.
- Date: at 4:30.
- Moonphase: integrated into the 6 o’clock hour counter.
Monochrome-Watches described the indications as legible and noted that the calendar displays do not overlap the chronograph registers.
Blue-edition case, dial and strap
The 2015 article specifies a 42 mm stainless-steel case measuring 12.75 mm high, with 50 m water resistance. It has a box-shaped sapphire crystal treated on both sides and a sapphire display back. The blue sunray dial is fitted with rhodium-plated applied indexes and hands with Super-LumiNova. A blue alligator-leather strap with a protective rubber lining completes the configuration.
What it cost at launch—and what is known now
Monochrome-Watches reported an approximate launch price of €8,500 for the blue 1,975-piece edition in 2015. That is a historical launch figure, not a current retail price or resale valuation. Current availability and market value for this specific blue edition are not established here.

The same article reported a starting price of $395 for Baz Persaud’s cufflinks at the time. That historical figure does not establish current pricing or stock.
The cufflinks are a separate accessory
The cufflinks were handmade solid-silver El Primero pieces by Baz Persaud, a New York-based artist. Monochrome-Watches described his process as “lost wax” and said the cufflinks were made with Zenith’s permission. They are not part of the watch’s specification or a bundled component of the edition.

Do not confuse this edition with other El Primero 410 watches
The name appears on distinct releases. Edition, year, movement, dimensions and quoted price matter when comparing them.
| Release | Production and price reported | Distinguishing details |
|---|---|---|
| Earlier El Primero 410, covered by Hodinkee in January 2014 | 500 pieces; $11,000 as reported in 2014 | 42 mm case; not the blue 1,975-piece 2015 edition. |
| Blue El Primero 410, covered by Monochrome-Watches in 2015 | 1,975 pieces; approximately €8,500 at launch | 42 mm steel case, blue sunray dial, blue alligator strap; 410 movement with 50-hour reserve. |
| Later Chronomaster Original Triple Calendar, Zenith 2024 press material | CHF 12,900 or CHF 13,400, depending on configuration | El Primero 3610; 38 mm case, approximately 60-hour reserve, 1/10-second chronograph, calendar and moonphase. |
Zenith’s 2024 description for the later model calls its calendar a “Complete Calendar (Day, Date & Month). Moonphase display.” Those later specifications and prices do not describe the 2015 El Primero 410.

Historical context
The 2015 article dates the El Primero’s unveiling to 1969 and describes it as one of the first automatic chronograph movements. It also notes that claims of priority depend on what counts—development, patenting, introduction, production or delivery—so an unqualified claim that it was “the first” oversimplifies a contested chronology.
The article also recounts a rare vintage prototype with a triple-calendar layout. It reports that an example from an estimated 25-piece production was sold by Christie’s in May 2012 for CHF 37,500, with Zenith as the buyer. That is historical context about the prototype, not a valuation for the blue 2015 edition.
