Our take on the Tandorio 40mm Quartz GMT Watch Black-10

The Tandorio 40mm Quartz GMT is a stainless steel travel watch built around the Swiss Ronda 515.24H movement, which drives a separate 24-hour hand so you can read two time zones at once. It pairs a sapphire crystal and 100m water resistance with a fixed bezel, a date window and green lume on a black or white dial. At 40mm wide and 12.5mm thick on a 20mm bracelet, it wears like a standard sports watch. It suits buyers who want GMT function and sapphire without paying for a mechanical movement; the trade-offs are a non-rotating bezel, a push/pull crown and a quartz tick rather than a sweep.

  • LumeMixedThe green lume is visible at night but several owners say it dims faster than expected.

About the Tandorio 40mm Quartz GMT Watch Black-10

This is a 40mm quartz GMT watch powered by a Swiss Ronda 515.24H GMT quartz movement. A 24-hour GMT hand lets it show a second time zone alongside the main time, and a calendar date window is included.

The case is solid 316L stainless steel with a fixed, non-rotating bezel and a sapphire crystal. The dial has green luminous indices and comes in white or black. The watch has a push/pull crown and a 20mm stainless steel bracelet with a clasp, and it is water resistant to 10ATM (100m).

Questions and answers

Does the GMT hand track a second time zone independently?
Yes. The Ronda 515.24H drives a separate 24-hour hand that you set to a second zone, so you read home and travel time at once.
Can I swim with it?
It is rated 10ATM (100m), which covers swimming and showering. The crown is push/pull, so keep it fully pushed in and avoid diving.
Is the bezel rotatable?
No. The bezel is fixed, so it does not add a third time zone the way a dive-style GMT bezel would.
What size wrist does the 40mm case suit?
The 40mm case and 12.5mm thickness fit most wrists, roughly 6.5 to 8 inches. The 20mm lug width takes standard straps.
Does it have a sapphire crystal?
Yes. The crystal is sapphire, which resists scratches far better than the mineral glass common at this level.
What comes in the box?
The watch on its stainless steel bracelet. Check the listing for any extra straps or tools, since bundles vary by seller.
