GMT under $500

Best GMT watches under $500

Until 2022 a mechanical GMT started around $2,000. Then Seiko put a 24-hour hand in the 5 Sports line and the floor collapsed.

By Sawyer V. · Published

The short answer

The Seiko 5 Sports GMT SSK001 is the answer under $500: a genuine, independently settable 24-hour hand on the 4R34, with Seiko's published $176 overhaul price. The SSK023 is the same watch in a 39.4mm case.

A GMT hand goes round once every 24 hours instead of twelve, read against a 24-hour scale. Set it to another time zone and you can see at a glance whether it is a reasonable hour to call somebody. That is the whole feature, and it is a good one.

Until Seiko put the 4R34 into the 5 Sports line, a mechanical version of it effectively started around $2,000. That is the only reason this page can exist at all.

Caller or flyer — the distinction that decides which to buy

  • Caller GMT. The local hour hand is fixed to the movement and you set the 24-hour hand independently. Right if you stay put and track a zone elsewhere. Seiko's 4R34 is a caller.
  • Flyer GMT. The local hour hand jumps in one-hour steps, so on landing you click it to local time and the reference zone keeps running. Right if you are the one moving — and considerably more expensive.

Most people buying a GMT are callers who have been told they need a flyer. If you have family two zones away and fly twice a year, a caller is the correct watch and it costs a fraction as much.

How we picked

We have not worn these watches. What follows is what we checked instead, on documents you can open yourself — the same criteria, in the same order, on every roundup on this site. The full method is on the methodology page.

  1. 01Caller or flyer

    Whether the 24-hour hand is independently set (caller) or the local hour hand jumps (flyer). Most buyers need a caller and are sold a flyer.

  2. 0224-hour scale legibility

    On a rotating bezel you can track a third zone; on a fixed rehaut it is cleaner and harder to read.

  3. 03Crystal

    Sapphire, hardlex, mineral or acrylic — decided at purchase, never after.

  4. 04Water resistance

    The rating in meters, and whether a screw-down crown sits behind it.

  5. 05Serviceability

    A named, in-production caliber with a service price you can look up.

  6. 06Fit

    Lug-to-lug, because a GMT case is usually thicker than the three-hand version of the same watch.

The 4R34 is a genuine caller GMT: the 24-hour hand is independently settable, and the movement sits in the same published $176 service band as the rest of the 4R family.

The rotating 24-hour bezel is the practical advantage over the SSK023 below — with it you can follow a third time zone as well as the one on the hand.

42.5mm, 46mm lug-to-lug, 13.6mm thick, Hardlex with a magnified date. Not refined; comfortably the best value in the complication.

The 4R34 is a caller GMT — the 24-hour hand is the one you set, not the local hand — but it is a real mechanical second time zone on a movement whose service price Seiko publishes.

Same 4R34, same $176 overhaul, in a case 3mm narrower and considerably less sporty-looking. If the SSK001 is too much watch, this is the same purchase in a size more wrists can carry.

47.9mm lug-to-lug means small-to-medium rather than genuinely small, and the bezel is fixed rather than rotating — so you lose the third-time-zone trick.

Identical movement and identical service cost to the SSK001 in a case 3mm narrower. If the 42.5mm SSK001 is too much watch, this is the same purchase in a size more wrists can carry.

38mm, a steel case, an 18mm lug width and a battery any shop can change for a few dollars. If what you want is the second time zone rather than the mechanism, this does the job for a fraction of the price.

The acrylic crystal is a genuine plus at this price — it scratches and polishes out with a cloth indefinitely. 50m and a one-year warranty that excludes the crystal, strap and case are the limits.

A quartz GMT at 38mm, with an acrylic crystal you can polish and a battery any shop can change. It is not built like the mechanical GMTs on this site, but nothing about it is expensive to keep running.

This is a very good watch — domed sapphire, 50m, a three-year warranty — and it turns up in GMT searches constantly because the dial has a 24-hour sub-register on it.

A 24-hour register is driven by the same hour hand you are already reading. It tells you whether it is 3am or 3pm in **your** time zone. It cannot be set independently and it cannot show another zone. It is an AM/PM indicator, not a GMT complication.

If you want a second time zone, buy one of the three above. If you want this watch, it is on our [dress watches under $500](/styles/dress-watches/best-under-500) page where it belongs.

Domed sapphire at this price is unusual and it is why this one is here. The 50.5mm lug-to-lug is not — that is a big watch, whatever the 42.5mm on the spec sheet suggests.

What to check on a GMT

  1. Caller or flyer, and whether you are paying for the one you need.
  2. Where the 24-hour scale lives. On a rotating bezel you can track a third zone; on a fixed bezel or rehaut it is cleaner and less flexible.
  3. Dial busyness. A GMT hand plus a date plus running seconds is a lot on a 40mm dial. Look at a photograph at actual size.
  4. Thickness. A GMT case is usually a little deeper than the three-hand version: the SSK001 is 13.6mm against 13.4mm for the SRPD55.
  5. The crystal. Seiko's entry GMTs use Hardlex, which is the clearest place the price is saved.

Mechanical or quartz

If the second time zone is the point, a quartz GMT does the job for far less and costs almost nothing to keep running. The Q Timex above is a steel-cased watch with an acrylic crystal you can polish yourself and a battery any shop stocks.

The argument for mechanical is the argument for mechanical everywhere: it can be rebuilt indefinitely, and Seiko publishes what that costs. A 4R34 sits in the same $176 band as the rest of the family, which makes an entry mechanical GMT one of the cheapest complications on this site to keep alive.

Questions people actually ask

What is the best GMT watch under $500?

The Seiko 5 Sports GMT SSK001 — a genuine caller GMT on the 4R34, with a rotating 24-hour bezel and Seiko's published $176 overhaul price. The SSK023 is the same watch in a 39.4mm case.

What is the difference between a caller and a flyer GMT?

On a caller, the 24-hour hand is independently adjustable and the local hour hand is not — right for tracking a distant zone from home. On a flyer, the local hour hand jumps in one-hour steps, which suits someone traveling. Flyers cost considerably more.

Is a 24-hour sub-dial the same as a GMT?

No. A 24-hour sub-register is driven by the same hour hand you are already reading and shows whether it is morning or evening in your own time zone. A GMT hand is set independently and shows a different zone.

Is a quartz GMT worth buying?

If the second time zone is what you want rather than the mechanism, yes — it costs a fraction as much and almost nothing to keep running. The Q Timex GMT is 38mm with an acrylic crystal you can polish yourself.
