Breitling Super Chronomat 44 Four-Year Calendar U19320161C1S1 Guide

The Breitling Super Chronomat 44 Four-Year Calendar reference U19320161C1S1 pairs Breitling's largest Super Chronomat sport case with a four-year calendar complication, built in two-tone stainless steel and 18ct red gold with a blue index dial and a rubber strap. It sits above the standard three-hand and chronograph versions of the Super Chronomat 44 in mechanical complexity, and below a true grand complication. This guide covers the specifications, what a four-year calendar actually corrects for, how the U19320161C1S1 compares with a black-dial sibling and with a simpler Breitling chronograph, how the 44mm case wears, price context, and what to check before buying. Bizak & Co. sources the U19320161C1S1 to order; the Breitling collection lists the configurations we can seek.

Breitling Super Chronomat 44 Four-Year Calendar U19320161C1S1 specifications

Breitling markets its mechanical watches as chronometer-certified, meaning each movement is tested to the tolerances set by the Swiss Contrôle Officiel Suisse des Chronomètres (COSC) before it leaves the factory. Full technical documentation for the current Chronomat and Super Chronomat range sits on Breitling's own watches pages, which we recommend checking against any reference before you order.

What does a four-year calendar correct for that an annual calendar does not?

A simple date watch needs a manual correction whenever a month runs shorter than 31 days, up to seven times a year. An annual calendar only needs correcting once, typically at the end of February, because it already knows which months have 30 and 31 days. A four-year calendar goes a step further: it also tracks the leap-year cycle, so the last manual correction it needs is at the end of a non-leap February, and it then runs correctly through the following leap year without another touch. For a daily-wear sport watch that is worn year-round rather than wound occasionally, that difference means the wearer sets the calendar far less often across the life of the watch.

How does the U19320161C1S1 compare with the black-dial I19320251B1A1?

Breitling lists more than one dial and case finish under the Super Chronomat 44 Four-Year Calendar name. The reference I19320251B1A1 carries a black dial rather than blue, on the same two-tone steel and red gold case, and was listed in Bizak's catalogue on 27 September 2026 at US$11,499 brand new, sourced to order, against US$16,399 for the blue-dial U19320161C1S1. Both share the four-year calendar function; the price and configuration gap reflects the specific reference and set Breitling assigned rather than a difference in complication. Buyers deciding between the two should treat the black dial as the quieter, less expensive route into the same complication, and the blue dial as the more overt option.

How does the U19320161C1S1 compare with the U19320161C1U1?

The U19320161C1U1 shares the same 44mm two-tone case and blue dial as the U19320161C1S1 but carries a different reference suffix, and Bizak's catalogue listed it on 27 September 2026 at US$17,749 brand new, sourced to order, a premium of roughly US$1,350 over the C1S1. Breitling's own suffix conventions vary by generation and are not always self-explanatory from the reference number alone, so buyers who care about the exact bracelet or strap fitted to a specific unit should confirm the configuration with us before ordering rather than assume it from the reference code.

How does the Super Chronomat 44 wear on the wrist?

At 44mm the case reads as a full-size sport watch on most wrists, closer in scale to a dive watch than to a classic dress chronograph. The two-tone build mixes stainless steel with red gold on the bezel and case accents; red gold runs warmer than yellow gold and cooler than rose gold, and against a blue dial the contrast is meant to be seen rather than understated. The rubber strap keeps the overall weight down despite the precious-metal content and is more water-friendly day to day than a leather strap would be on a watch this size. The uni-directional ratcheted bezel gives a tactile click that most owners use for elapsed-time timing rather than diving, since the watch's identity is sport-luxury rather than tool-dive.

How much does the Super Chronomat 44 Four-Year Calendar cost in 2026?

• Bizak catalogue, 27 Sep 2026. The blue-dial U19320161C1S1 listed at US$16,399, the same case on the U19320161C1U1 at US$17,749, and the black-dial I19320251B1A1 at US$11,499, all brand new and sourced to order.
• What drives the spread. Dial colour, the exact reference suffix and whatever set and box Breitling shipped with a given unit all move the number; two watches that look similar in photographs are not always priced the same.
• How to read any figure here. These are catalogue asks on the date stated, not live quotes. Breitling's own current retail pricing for the range sits on its watches pages, and we recommend checking there for the manufacturer's list price before comparing it with a sourced ask.

What to check before buying a Super Chronomat 44 Four-Year Calendar

• Confirm box and papers. A brand-new watch should come with its original box, warranty card and full documentation, with the serial number on the papers matching the case.
• Inspect the case and bezel closely. Even new stock can pick up handling marks in transit; check the red gold accents, bezel edge and lug faces under strong light before you accept the watch.
• Verify the four-year calendar function. Ask the seller to walk you through setting and reading the day, date, month and four-year indicators, and confirm each advances correctly at midnight.
• Test the rubber strap and clasp. On a new watch the strap should flex cleanly and the folding clasp should close with no stiffness or play.
• Match the reference exactly. Confirm the full reference code, dial colour and strap or bracelet fitted against the listing before you commit, since Super Chronomat 44 references vary in ways that are not always obvious from a photograph.

Is the U19320161C1S1 worth it against a simpler Breitling chronograph?

Buyers who ask for this reference have usually already owned a chronograph or a simple date watch and want the step up that a genuine calendar complication provides. A more affordable route into the same Chronomat family is the Breitling Chronomat B01 42 PB0134101C1S1, a 42mm steel and platinum three-register chronograph with an ice-blue dial, listed in Bizak's catalogue on 27 September 2026 at US$8,999 brand new, sourced to order. It has no calendar complication and a smaller case, so it suits a buyer who wants Breitling's chronograph identity without the four-year calendar's mechanism or the larger 44mm footprint. The U19320161C1S1 is the watch to choose if the calendar function and the larger, two-tone case are specifically what you are after; the B01 42 is the watch to choose if you want a lower entry price and a more compact daily wearer.

Who is the U19320161C1S1 for?

This reference suits a buyer who wants a serious sport complication without moving to a full precious-metal case. The four-year calendar adds genuine daily-use value over a plain date window, and the red gold accents add warmth without pushing the watch into formal-wear territory. A buyer who wants one watch to cover both a boat weekend and a dinner reservation is the person this reference is built for; a buyer who wants the smallest possible entry price into the Chronomat family should look at the B01 42 instead.

Quick answers

What is the Bizak catalogue price for the Breitling Super Chronomat 44 Four-Year Calendar U19320161C1S1?

Bizak's sourced catalogue listed the blue-dial U19320161C1S1 at US$16,399 brand new on 27 September 2026, sourced to order. Contact us for a dated quote before you commit, since this figure will move.

How does the 44mm case size wear in practice?

The case measures 44mm across, which reads as a full-size sport watch. The rubber strap helps distribute the weight and keeps daily wear comfortable despite the two-tone case materials.

What makes a four-year calendar different from a standard annual calendar?

An annual calendar needs one manual correction a year, usually at the end of February. A four-year calendar also tracks the leap-year cycle, so its last correction before a leap year holds through that extra day without another touch.

What is the difference between the U19320161C1S1 and the black-dial I19320251B1A1?

Both share the same four-year calendar complication and two-tone steel and red gold case. The I19320251B1A1 carries a black dial and was listed at US$11,499 on 27 September 2026, against US$16,399 for the blue-dial C1S1; the gap reflects the specific reference and set rather than a difference in mechanism.

Is Breitling's Super Chronomat range chronometer certified?

Breitling positions its mechanical watches as chronometer certified, meaning each movement is tested against the tolerances set by the Swiss COSC testing body before it ships. Details of that certification sit on the COSC website linked above.
