Stepping up in Tudor's range
The Royal name has been in Tudor's vocabulary since the 1950s, and its return as a modern collection was a deliberate repositioning — a sport-chic alternative to the more tool-oriented pieces in the range. The integrated bracelet, notched fixed bezel and screw-down crown give it a coherent visual logic, and this black-dialled reference layers dressy detail onto that sporty architecture: eight brilliant-cut diamond hour markers sit alongside applied gold-tone Roman numerals at the quarters, making the dial do two jobs at once without looking conflicted. At 10.6mm thick for a 41mm case, it wears closer to the wrist than the category usually allows, and the absence of traditional protruding lugs — the case flows straight into the bracelet — keeps the 45mm lug-to-lug span from sitting proud on smaller wrists. The two-tone bracelet pairs satin-brushed outer rows with polished intermediate links, which echoes the dial's own combination of sparkle and restraint. The T603 inside draws on proven Swiss lever-escapement architecture that Tudor has modified for their own tolerances; it is not a manufacture movement, but it is one of the more honestly reliable calibres in the automatic segment, and it is straightforward to service when the time comes.

Learn more about Tudor
Tudor exists because Hans Wilsdorf wanted to sell a Rolex to people who could not afford one. He registered the name in 1926 and relaunched it properly in 1946 as a separate company: Rolex cases, Rolex bracelets, Rolex crowns, but bought-in movements — usually ETA — at a fraction of the price.
For decades this made Tudor the practical choice for organisations buying in bulk. The French Marine Nationale issued Submariners to its divers. The US Navy tested them. Tudor's military history is arguably richer than Rolex's, because navies bought Tudors.
The watches developed their own identity regardless. The snowflake hands fitted to Submariners from 1969, specified by the French navy for legibility, became a signature the brand still uses. The Monte Carlo chronographs of the early 1970s, with their orange and blue dials, look nothing like anything Rolex made.
The brand withdrew from the US market in 1996 and spent a decade in relative obscurity before returning in 2013 with the Heritage Black Bay, which mined the archive rather than chasing modernity. It worked. Tudor now develops its own movements through a partnership with Kenissi, supplies calibres to Breitling, and holds METAS Master Chronometer certification — a technical position it never had when it was simply the affordable Rolex.

Frequently asked questions, and things you should know about this watch
Can I swim with it?
Yes. At 100m it is rated for swimming and snorkelling, though not for diving.
Water resistance explainedWill the glass scratch?
Unlikely. Sapphire is second only to diamond in hardness and shrugs off everyday marking.
Sapphire, mineral and acrylic comparedDoes it need a battery?
No. It is automatic — the motion of your wrist winds it, and there is no cell to replace.
Quartz, automatic and solar comparedHow long does it run for when it's not worn?
About 38 hours fully wound — so it will usually stop if you leave it off overnight.
Will it fit my wrist?
Lug-to-lug is 45mm, which suits wrists from roughly 16cm (6¼ inches) upward.
Lug-to-lug decides fit more than case diameter does.
How to size a watch to your wristIs it a men's or women's watch?
Listed as men's.
