Citizen Tsuyosa 60 Automatic Features New Caliber 8310 with Extended Power Reserve
Citizen has announced a significant upgrade to its bestselling Tsuyosa collection with the launch of the Tsuyosa 60 Automatic. According to Monochrome Watches, the new model introduces the Caliber 8310 movement, replacing the Caliber 8210 found in the standard automatic versions, while also adding a new guilloche-style dial texture and a refined Jubilee-style bracelet.
Caliber 8310: More Power, Better Finishing
The centerpiece of the Tsuyosa 60 Automatic is the new Caliber 8310, an in-house automatic movement that represents a meaningful upgrade over its predecessor. According to Monochrome Watches, the movement runs at a frequency of 3Hz (21,600 vibrations per hour) and delivers an extended 60-hour power reserve, a 50% improvement over the 40-hour capacity of the Caliber 8210.
| Specification | Caliber 8210 (Old) | Caliber 8310 (New) |
|---|---|---|
| Power Reserve | 40 hours | 60 hours |
| Frequency | 3Hz (21,600 vph) | 3Hz (21,600 vph) |
| Jewels | 21 | 21 |
| Finishing | Unfinished brass | Silver-toned, striped bridges |
| Rotor | Solid | Openworked |
| Screws | Standard | Blue-coloured |
Beyond the power reserve improvement, the Caliber 8310 features substantially better finishing. According to Monochrome Watches, the movement now sports silver-toned bridges and plates, an openworked rotor adorned with the Mido logo, blue-coloured screws, and decorative striping on the main bridge. This level of decoration is typically reserved for watches at significantly higher price points.
Design Evolution
The Tsuyosa 60 Automatic maintains the 40mm case diameter of the original Tsuyosa but introduces several refinements. According to Monochrome Watches, the watch features a stamped guilloche-like pattern on the dial, adding depth and visual complexity. This texture was previously only available on the Tsuyosa Small Second variant, and its introduction to the central-seconds model responds to customer demand.
The collection launches in three variants: an uncoated steel version with a black dial (NK0020-55E), a bi-colour model with rose gold IP-coated bezel and crown paired with a green dial (NK0024-54X), and a fully rose gold IP-coated version with a blue dial (NK0023-57L). Each variant features applied markers and hands filled with luminous material for enhanced legibility.
New Jubilee-Style Bracelet
Another significant change is the introduction of a 5-link Jubilee-style bracelet, replacing the 3-link design of the standard Tsuyosa. According to Monochrome Watches, the new bracelet features brushed external links with polished central links, creating a more refined aesthetic. The clasp has been upgraded to a concealed butterfly construction for better integration with the overall design.

Value Proposition in Context
The Tsuyosa 60 Automatic represents Citizen's strategy of offering meaningful upgrades at accessible price points. According to Monochrome Watches, the original Tsuyosa collection launched in 2022 and quickly became one of the brand's bestselling models by combining 1980s design inspiration with integrated sports watch aesthetics. The Tsuyosa 60 builds on this success by delivering movement and finishing improvements that punch well above its price class.
