Why smaller is better: the rise of sub-40mm chronographs
According to Monochrome Watches, the watch industry has seen a quiet revolution in recent years: the rise of chronographs that don’t compromise on size. As of March 2026, while traditional chronographs often demand cases exceeding 40mm to house their intricate mechanisms, a new wave of designs proves that complexity and compactness can coexist. This trend isn’t just about aesthetics, it reflects a broader shift in consumer preferences toward wearable, versatile timepieces that fit seamlessly into daily life.
“The demand for smaller chronographs is driven by both practicality and style,” says Marc Dubois, a horology analyst at the Swiss Watch Industry Association. “Modern buyers want to carry their watches without sacrificing functionality, and brands are answering with technically advanced, elegantly scaled designs.”
Longines spirit flyback chronograph 39mm
Longines’ Spirit Flyback Chronograph 39mm is a prime example of this evolution. At 39.5mm in diameter and 13.4mm in height, it’s a slimmer iteration of the brand’s earlier 42mm model. The steel case, brushed and polished, pairs with a ceramic bezel and sapphire crystal, offering both durability and a polished finish. A matte black dial with gilt markers and SLN-treated hands adds a touch of retro elegance without overwhelming the compact form.
Powering this watch is the manually wound Calibre L792.4, a COSC-certified chronometer known for its precision. Running at 28,800vph (4Hz), it provides a 68-hour power reserve, proof of efficient engineering. Available on leather or steel, it retails for EUR 5,150 to EUR 5,400. “This model bridges the gap between vintage charm and modern wearability,” notes Dubois.
Atelier nossedh an.01: A minimalist marvel
At 37mm in diameter and 10.5mm in height, the Atelier Nossedh AN.01 is one of the smallest chronographs on this list. Its bicompax layout—featuring a black or colored dial with applied hour markers—evokes 1950s aviation chronographs. The leaf-shaped hands and polished accents create a striking contrast against the dial, while the sapphire caseback reveals the Sellita SW510 M movement, which delivers a robust 63-hour power reserve.
At EUR 2,200, it’s one of the most affordable options. “The AN.01 is a sleeper hit,” says horology blogger Clara Voss. “It’s not just about size, it’s about making a statement with minimalism.” The Epsom leather strap and steel pin buckle add a touch of understated luxury, making it versatile for both casual and formal settings.
Audemars piguet royal oak chronograph 38mm
Audemars Piguet’s Royal Oak Chronograph 38mm is a bold departure for the brand. At 38mm wide and 11.1mm tall, it’s the smallest Royal Oak chronograph ever produced. The 38mm case, available in steel or pink gold, houses the new Calibre 6401; an in-house automatic column-wheel chronograph. The blue, grey, or rose gold dials feature the iconic tapisserie pattern, while the contrasting subdials and applied markers emphasize the watch’s mechanical complexity.
Prices range from CHF 34,000 to CHF 72,400, reflecting the brand’s heritage and craftsmanship. “This model redefines what a Royal Oak can be,” says Dubois. “It’s a technical triumph that doesn’t sacrifice the brand’s signature style.”
Lebois co heritage chronograph: A vintage revival
Lebois Co’s Heritage Chronograph takes inspiration from the 1950s, with its eggshell Grand Feu enamel dial and bicompax layout. At 39mm wide and 14.3mm tall, it’s a slightly larger but still compact offering. The steel case with shaped pushers and knurled crown gives it a robust feel, while the manually wound Calibre LC-480 (La Joux-Perret) ensures precision. Limited to 25 pieces annually, it’s a collectible piece at EUR 9,800.
“This is the kind of watch that feels like a relic but functions like a modern marvel,” says Voss. “The enamel dial alone makes it a standout.”
Zenith chronomaster original blue: timeless design
Zenith’s Chronomaster Original Blue is a tribute to the 1969 El Primero A386, reimagined in a 38mm case. The midnight blue dial, with its tricolour subdials and 1/10th-of-a-second scale, is a nod to the brand’s racing heritage. The fully integrated Calibre El Primero 3600 runs at 36,000vph, offering precise chronograph measurements. Priced at EUR 10,400, it’s a timeless classic with a modern twist.
“Zenith has always balanced innovation with tradition,” Dubois notes. “This model is proof that the past can inspire the future.”
Raymond weil millésime chronograph: retro meets modern
Raymond Weil’s Millésime Chronograph merges vintage charm with contemporary design. At 39mm wide and 12.9mm tall, it features a black or anthracite dial with contrasting subdials and luminous markers. The Sellita-based Calibre RW5030 delivers a 62-hour power reserve, and the watch is available in stainless steel or rose gold PVD. Priced from EUR 3,725 to EUR 3,895, it’s a budget-friendly option for retro enthusiasts.
“Raymond Weil’s approach is all about accessibility,” says Voss. “It’s a watch that feels expensive without breaking the bank.”
The future of chronography: smaller, smarter, more versatile
As the industry moves toward more wearable designs, sub-40mm chronographs are proving that complexity doesn’t have to come at the cost of size. These watches cater to a growing demographic—business professionals, travelers, and collectors; who want to balance functionality with aesthetics. With advancements in movement miniaturization and materials, the future of chronography is likely to see even more innovation in compact formats.
“The trend is here to stay,” predicts Dubois. “Brands that embrace this shift will dominate the next decade.” Whether you’re drawn to the vintage flair of the Atelier Nossedh AN.01 or the prestige of the Audemars Piguet Royal Oak, these watches exemplify the potential of mechanical chronographs in smaller packages.
