What is the Go0fy Panda Gen3?
It is a mechanical chronograph in Studio Underd0g’s 01SERIES. The manufacturer presents the Go0fy Panda as a playful interpretation of the traditional panda dial, using a two-layer dial and bi-compax subdial arrangement. The green-tipped chronograph hand adds a contrasting detail. These are the brand’s design descriptions, rather than independent performance assessments. See the official Go0fy Panda product page and the 01SERIES collection.

How the dimensions may affect fit
The 44.5 mm lug-to-lug measurement is useful when judging how far the watch may span across the wrist, while 38.5 mm is its case diameter. The stated 12.9 mm thickness is the overall figure, not a measure of how the watch will sit on every wrist. Dimensions alone cannot establish fit: wrist shape, strap flexibility and personal preference matter. If possible, compare the measurements with a watch you already wear or try the Go0fy Panda on in person.
What to know about the manual ST-1901B
The ST-1901B requires hand winding rather than winding from wrist motion. Studio Underd0g describes it as a Seagull manual-winding calibre developed in partnership with Seagull and exclusive to the brand. Its published reserve differs depending on chronograph use: 50 hours with the chronograph off and 45 hours with it running. The stated accuracy range is -10 to +15 seconds per day. These are manufacturer specifications, not independently verified test results.

#1 Best Overall
- VK63 MECHA-QUARTZ CHRONOGRAPH: The WD1863 uses a VK63 mecha-quartz movement with a central 1/5-second chronograph hand, 60-minute counter, running small seconds and a 24-hour display. The pushers control start, stop and reset, combining quartz accuracy with crisp mechanical-style chronograph action for practical elapsed-time measurement.
- BUBBLE SAPPHIRE CRYSTAL & ALUMINUM BEZEL: The raised bubble-style sapphire crystal adds depth above the dial, while a high-clear inner AR coating helps reduce reflections. A 316L stainless steel case and bracelet provide a solid everyday build, and the fixed aluminum bezel creates a defined frame around the vintage chronograph display.
- SUPER BGW-9 BLUE LUME: BGW-9 super luminous material is applied to the hands, hour markers and selected dial details. After exposure to light, these elements produce a blue glow that supports quick time reading in darker surroundings. Coverage follows the individual dial design and remains clearly arranged around the three-register chronograph display.
- 100M WATER RESISTANCE: The screw-down crown and screw-down case back support a 100M water-resistance rating for daily wear and suitable surface-water use. Always tighten the crown fully before contact with water, do not operate the chronograph pushers while the watch is wet or submerged, and avoid hot water, steam and diving. Water resistance should be checked periodically as seals age.
- COMPACT 39MM WRIST PROFILE: The WD1863 measures 39mm across the bezel, with a 41mm mid-case, 46mm lug-to-lug length, 12.9mm thickness including the raised crystal and 20mm lug width. These proportions balance the detail of a three-register chronograph with a wearable footprint. The 20mm bracelet remains proportionate to the case, while the raised crystal adds vintage depth to the compact design.
Strap fit and replacement options
The lug width is 20 mm, and the supplied strap tapers to 16 mm. A replacement marketed as a “20 mm quick-release watch strap” matches the stated lug width and spring-bar style, but width alone does not guarantee a suitable fit. Check the replacement’s taper, buckle dimensions and material, as well as whether it uses quick-release spring bars.
