The Tudor Royal in two-tone with diamonds. The 2020 generation.

The Tudor Royal of 2020 was the brand’s integrated-bracelet watch, the notched bezel and five-link bracelet of the 1970s Rolex Oysterquartz idea at a Tudor price, with a bought-in automatic, the T603, rather than a manufacture calibre. The two-tone version with a diamond champagne day-date dial was the top of the range. In 2025 Tudor relaunched the Royal with new references, which is why the M28603 is no longer on tudorwatch.com.

The reference is discontinued and no longer on tudorwatch.com, so the calibre, reserve and 100 metres are Tudor’s figures as published when it was current, and the copy states no thickness or lug width. The diamonds are hour markers only; the bezel is plain notched gold.

The listing carries the reference M28603-0006 in the title and model row and calls it a Royal automatic with a diamond champagne dial, 41mm, 100 metres and a steel and 18kt yellow gold band. The photograph shows the notched gold bezel, the diamond dial with day and date, and the integrated two-tone bracelet. The calibre and reserve are Tudor’s figures for the reference at launch.

The seller is MS-TR JAPAN, a marketplace seller. Ask the seller whether it is new with Tudor’s five-year guarantee card, and for the box; the rows we read do not say. Nothing here was measured on the watch.

This is a regular Amazon listing from a marketplace seller with Amazon’s 30-day return window; it is not a Luxury Stores pre-owned unit and the seller has not published a condition. The second button opens the live search for Tudor Royals in case this one has sold.

Royals have resold for under new and close to what pre-owned buyers paid, sometimes more, sometimes less; that is a pattern, not a promise, and nothing here is investment advice.
