The Hamilton Jazzmaster Performer is a sport-chic family rather than one watch in three sizes: it includes 34mm and 38mm time-only automatics, plus a larger 42mm automatic chronograph. The smaller references lean toward a versatile everyday or dress-watch profile; the chronograph adds a tachymeter bezel, subdials and substantially more wrist presence. Which one suits you depends on the size, complication and configuration you want—and whether the specific reference is still offered in your region.
What makes the Jazzmaster Performer different?
Hamilton positions the Performer as a balance of technical performance and urban style, calling the collection “Sport-chic timepieces built for any challenge.” That is brand positioning, not independent proof of performance. In practical terms, the range bridges dressier styling and sport-watch details: polished or dark-finished cases, varied dial colors, steel bracelets and perforated racing-style leather straps.
The lineup is not uniform. The 34mm and 38mm watches are time-only automatics, while the 42mm version is an automatic chronograph. A fixed tachymeter bezel and chronograph controls give the larger model a more overtly sporty look, while the smaller watches have a cleaner dial and slimmer case profile. Hamilton describes bracelet and perforated leather-strap options across the family; check the exact reference before assuming a strap or bracelet will fit another model.
How do the three sizes compare?
The most useful sizing comparison in Monochrome Watches’ 1 March 2023 hands-on report includes thickness as well as diameter. The chronograph is markedly thicker than either time-only model, so its 42mm diameter alone understates how substantial it may feel on the wrist.

| Variant | Diameter | Thickness | Movement and display |
|---|---|---|---|
| Time-only automatic | 34mm | 11.18mm (Monochrome, March 2023) | H-10 automatic; hours, minutes and seconds |
| Time-only automatic | 38mm | 11.47mm (Monochrome, March 2023) | H-10 automatic; hours, minutes and seconds |
| Automatic chronograph | 42mm | 15.22mm (Monochrome, March 2023) | H-31 automatic chronograph; subdials and date |
These dimensions come from the 2023 report and describe the models covered there; confirm the exact reference specifications when comparing later releases. The 34mm is the compact choice, the 38mm offers more dial presence without moving to a chronograph, and the 42mm has the most imposing profile and the additional thickness associated with its complication.
What does each movement offer?
H-10 in the time-only models
Monochrome reports an 80-hour power reserve and Nivachron balance spring for the H-10 in the time-only Performer models. Hamilton’s product page for the blue-dial 38mm H36235140 also specifies the H-10, an 80-hour reserve and Nivachron. That reference’s page lists an open case back, sapphire crystal and Super-LumiNova as well.

H-31 in the chronograph
Monochrome’s 2023 report describes the 42mm chronograph’s H-31 as based on Valjoux 7753 architecture, operating at 4 Hz, with a 60-hour power reserve. Swatch Group’s January 2025 announcement for a black PVD Auto Chrono likewise specifies a 60-hour reserve and Nivachron balance spring. These are source- and model-specific specifications, not a blanket claim for every chronograph release: published figures have differed, so check the exact reference’s official specification before relying on a reserve figure.
The tachymeter bezel is used with the chronograph hand to estimate average speed over a measured distance. The 2023 report also notes three subdials, a date display, luminous hands and markers, and an exhibition case back on the chronograph it covers. The complication makes the watch more functional for timing, but it also makes the face busier than the time-only models.

What is the 38mm H36235140?
Hamilton’s regional product page identifies H36235140 as a 38mm automatic with a blue dial and steel bracelet. The listed specifications include a 20mm lug width, 100m water resistance, screw-down crown, sapphire crystal, open case back, H-10 movement with 80-hour reserve, Nivachron balance spring and Super-LumiNova. Hamilton labels this reference “Past collection,” so the page documents the model but does not establish current stock or sale availability.
A 20mm lug width is useful when considering replacement straps, but width alone does not guarantee compatibility. End shape, attachment and any reference-specific bracelet geometry matter; verify those details for H36235140 or the particular watch you own before ordering.

Which configuration is right for you?
- Choose the 34mm time-only model if you want the smallest case and a simpler dial. Reported configurations include blue or black bracelet options and a mother-of-pearl dial with satin strap.
- Choose the 38mm time-only model if you want a middle ground in size with the H-10 movement. Reported configurations include blue strap, black dial on steel bracelet, and rose-gold PVD treatments.
- Choose the 42mm chronograph if you want timing functions and a more assertive sport-watch appearance. Its tachymeter bezel, three subdials and 15.22mm reported thickness make it the most visually and physically substantial option of the 2023 group.
Finish and strap can change the character as much as diameter. Steel bracelets tend to make the watch feel more integrated and substantial; perforated racing-style leather gives the family a more explicitly sporty note. Later releases have varied the palette: Swatch Group Japan’s April 2024 announcement described a pale-blue 42mm chronograph, a white-dial 38mm model and additional 34mm colors. Those are Japan-specific release details, not evidence that the same references are available worldwide now.
