The Best GMT Watches for Travellers and Serious Collectors
GMT watches are one of the most practical complications you can wear on your wrist, letting you track two time zones at a glance without touching the crown. Whether you're a frequent flyer, a remote worker managing international calls, or a collector drawn to the aesthetic of a fourth hand, there's a GMT watch built for you. The complication traces its roots to 1954, when Pan Am commissioned Rolex to build a watch for their pilots and the category has never looked back.
What Makes a Great GMT Watch
Not all GMT watches work the same way, and understanding the difference will make you a much smarter buyer. There are two main types: the "traveller" GMT and the "office" GMT. A traveller GMT lets you independently adjust the local hour hand without disrupting the home time on the GMT hand, making it ideal for people who actually cross time zones. An office GMT moves both hands together, which is better suited to someone managing overseas calls from a fixed location.
The bezel plays a major role in how you read a GMT watch. Most feature a 24-hour graduated bezel, usually in ceramic or aluminium, which you align with the GMT hand to read a second or third time zone. Ceramic bezels resist scratching and hold their colour over time, while aluminium bezels develop character with wear and can be replaced more easily.
Movement quality is where the real separation happens between GMT watches at different price points. Entry-level options often use modified Sellita or ETA base movements, while premium options run certified in-house calibres with better accuracy, finishing, and longevity. For collectors, a COSC-certified movement adds genuine credibility to both the watch and its resale case.
Case size is another consideration. The 39mm sweet spot has become a favourite among collectors because it echoes vintage proportions while sitting comfortably on a wide range of wrists. Larger 40–42mm cases offer more dial presence and legibility, which suits the practical traveller who needs to read the time at a glance. Before buying any GMT watch, it helps to consult a dedicated GMT watch guide to understand how the complication works in everyday use.
The Best GMT Watches to Buy Right Now
Rolex GMT-Master II "Pepsi" (Ref. 126710BLRO)
The Rolex GMT-Master II is the benchmark by which all other GMT watches are judged. It features a red and blue bicolour Cerachrom ceramic bezel, a 40mm Oyster case, and the in-house Calibre 3285 movement with a 70-hour power reserve and Chronergy escapement. The Jubilee bracelet version, known informally as the "Pepsi," is considered the most desirable configuration in the current lineup.
On the secondary market, this reference consistently trades well above retail, reflecting the sustained demand and limited authorised dealer supply. For Australian collectors, acquiring one through grey market dealers typically means a premium of 40–70% over the retail price, but the long-term value retention makes it one of the most defensible purchases in the category.
Tudor Black Bay GMT 58
The Tudor Black Bay 58 GMT is built around a 39mm case with a METAS-certified MT5450-U movement rated to resist magnetic fields up to 15,000 gauss. The "Coke" black and red bezel version has become one of the most talked-about GMT watches in the mid-range, delivering comparable build quality to its Rolex sibling at a fraction of the price.
At around AUD $8,000 retail, the Black Bay 58 GMT represents exceptional value and trades solidly on the pre-owned market. Its accessible price point, wearable case size, and Tudor's growing collector profile make it one of the strongest entry points into serious GMT ownership available today.
Longines Spirit Zulu Time
The Longines Spirit Zulu Time offers true traveller GMT functionality with a COSC-certified movement at a retail price that undercuts most competitors in its category. The 39mm steel case pairs with a fixed 24-hour bezel scale, and the yellow GMT hand is easy to read at a glance in all lighting conditions.
For buyers who want genuine GMT utility without the premium attached to Swiss prestige brands, the Spirit Zulu Time is a compelling proposition. It holds its value reasonably well on the pre-owned market and is widely available through authorised retailers across Australia, making it one of the most accessible GMT watches at this quality level.
Omega Seamaster Planet Ocean GMT
The Omega Seamaster Planet Ocean 600M GMT runs on an in-house Co-Axial Master Chronometric movement and offers 600 metres of water resistance in a 43.5mm stainless steel case. The crown sits at 10 o'clock, and the high-contrast bicolour ceramic bezel makes this one of the most legible dual-zone diver GMT combinations available.
For collectors who want a GMT that doubles convincingly as a serious diver, the Planet Ocean is hard to overlook. Omega's standing in the secondary market is strong, particularly for steel sports references, and the watch benefits from the brand's global service network, which includes authorised service centres in Australia's major cities.
Buying GMT Watches in Australia: What You Need to Know
The Australian market for GMT watches has matured considerably over the past decade, with both the grey market and authorised dealer network becoming more sophisticated. Sydney and Melbourne are home to flagship boutiques for Rolex, Tudor, Omega, and Longines, giving local buyers the rare advantage of being able to try watches in person before committing. That said, high-demand references like the Rolex GMT-Master II remain extremely difficult to acquire at retail through authorised dealers without an established purchase history.
Grey market dealers operating across Sydney, Melbourne, Brisbane, and online are typically the most realistic route to securing sought-after GMT watches without a lengthy wait. Prices are higher than retail but come with traceability and, in most cases, manufacturer's warranty cards. Always verify that any pre-owned GMT watch comes with its box and papers, as these significantly impact resale value in the Australian collector community.
The Australian dollar plays a meaningful role in how GMT watch prices compare to international markets. When the AUD is weaker, grey market prices on imported stock tend to push higher, making European travel purchases an attractive option for buyers with trips planned. Platforms like Chrono24 and WatchBox have also made it easier for Australian collectors to access verified pre-owned GMT watches with international buyer protections.
Here is a quick-reference guide to the best GMT watches at each price tier for Australian buyers:
Under AUD $1,500: Seiko 5 GMT SSK series. Reliable, widely available, great entry point into the complication.
AUD $1,500–$5,000: Longines Spirit Zulu Time or Baltic Aquascaphe GMT. COSC-certified movements with genuine Swiss pedigree.
AUD $5,000–$10,000: Tudor Black Bay GMT 58. The strongest value proposition in mid-range GMT watches.
AUD $10,000–$20,000: Omega Seamaster Planet Ocean GMT. In-house movement, exceptional build quality, strong service network.
AUD $20,000+: Rolex GMT-Master II. The ultimate travel watch for collectors with long-term investment potential.

Best GMT Watches FAQs
A traveller GMT lets you independently adjust the local hour hand without affecting the home time shown on the GMT hand. This makes it genuinely useful for people who physically cross time zones and need to update their local time after landing without stopping the watch.
An office GMT moves both the local and GMT hands together, so you can only set a reference time zone separately by aligning the GMT hand to the 24-hour bezel. This suits people who stay in one place but regularly communicate with colleagues or clients in other time zones.
Certain GMT watches hold and appreciate in value very well, particularly steel sports models from Rolex. The GMT-Master II consistently trades above its retail price on the secondary market, driven by limited supply and sustained collector demand.
Mid-range GMT watches from brands like Tudor and Longines offer solid value retention rather than significant appreciation. They are strong buys for collectors who prioritise wearability and quality over pure investment returns. As with any watch purchase, condition, box and papers, and provenance all influence resale outcomes significantly.
The bezel on a GMT watch is divided into 24 hours rather than 60 minutes, allowing you to read a second time zone using the GMT hand. To use it, you rotate the bezel so that 12 o'clock on the 24-hour scale aligns with the reference time zone you want to track, then read off where the GMT hand points.
For example, if it is noon in Sydney and you want to know the time in London, you set the bezel so the Sydney time aligns correctly, and the GMT hand will point to the London hour on the 24-hour scale. Most entry-level GMT guides walk through this setup in detail if you want a hands-on demonstration.
The Tudor Black Bay GMT 58 is widely regarded as one of the best GMT watches for everyday wear. Its 39mm case size sits comfortably on most wrists, the METAS-certified movement offers strong magnetic resistance for urban environments, and the build quality is robust enough for daily use.
The Longines Spirit Zulu Time is another excellent daily wearer, particularly for buyers who want COSC-certified accuracy at a more accessible price. For those on a tighter budget, the Seiko 5 GMT series offers reliable GMT functionality, solid water resistance, and a tough stainless steel case that handles everyday wear without issue.
Authorised dealers and brand boutiques in Sydney and Melbourne offer the widest range of GMT watches at retail pricing, including boutiques for Rolex, Tudor, Omega, and Longines. However, high-demand references like the Rolex GMT-Master II often require an established purchase history to access at retail.
Reputable grey market dealers across Sydney, Melbourne, and Brisbane stock a wider range of references at above-retail prices, typically with box and papers intact. Online platforms like Chrono24 and WatchBox also serve the Australian market and offer buyer protections that make them a trustworthy option for pre-owned purchases.
