Tudor 1926 Luna: Moon Phase Specs and Prices

Tudor’s First Moon Phase

Tudor has built dive watches, chronographs, GMT travellers and even a fixed-lug military model, but until the 1926 Luna arrived in late 2025 the brand had never released a watch with a moon phase indicator. That makes the Luna a genuine first for a company with eight decades of production history — and it places the complication inside Tudor’s most affordable stainless steel dress collection rather than a limited run priced to match.

The 1926 collection itself launched in 2018 as Tudor’s answer to the entry-level dress watch segment. With sizes from 28 mm to 41 mm, diamond-set dial options and retail prices starting below $2,000, it occupies a tier well below the Black Bay family. Adding a moon phase complication to that foundation rather than to a Black Bay or Pelagos was a deliberate move: it keeps the retail price at $3,000, roughly a thousand dollars below most Swiss-made moon phase competitors on a bracelet.

The name “Luna” refers to the moon, naturally, but also nods to the date Tudor was founded — 1926 — and the classical tone the collection aims for. With a domed sapphire crystal, applied Arabic numerals and a polished bezel, the watch reads more like a Longines Master or a Frederique Constant Classics than a typical Tudor sports piece. Whether that shift appeals or not depends on what you want from the brand, and the rest of this guide covers the technical details that will help you decide.

Full Specifications

The Tudor 1926 Luna shares its 39 mm case diameter with the standard 1926 39 mm time-and-date models. The addition of the moon phase sub-dial at 6 o’clock adds roughly 1 mm of case thickness, bringing the total to 10.1 mm. That is still noticeably thinner than the Pelagos 39 at 12.8 mm, making the Luna a genuine dress-watch profile.

Three Dials, Three Personalities

Tudor launched the 1926 Luna in three dial colours, each at the same $3,000 retail price. All three share the same sunray-brushed finishing, applied Arabic numerals at even hours and faceted triangular indices at odd hours. The date aperture sits at 3 o’clock, while the moon phase indicator occupies 6 o’clock behind a polished bevel.

None of the three dials feature luminous material on the hands or indices. That is a deliberate design choice — the Luna is a dress watch, not a tool watch — but it does mean reading the time in a dark restaurant or cinema requires the Indiglo-era move of angling the watch toward a light source.

The T607-9 Movement Explained

The Calibre T607-9 is not an in-house Tudor movement. It is based on the Sellita SW280-1, a moon phase module built on the workhorse SW200 automatic platform. Tudor finishes the movement with machined striping, perlage and gold-filled engraving on the rotor — all hidden behind a solid caseback you will never see without a case opener.

That sourcing decision matters for two reasons. First, it keeps the retail price at $3,000 rather than the $3,700–$4,000 range that an in-house MT-series calibre would require. Second, the Sellita base means any qualified independent watchmaker can service the watch without proprietary Tudor parts. The counterpoint is that Tudor’s in-house movements — like the MT5402 in the Black Bay — offer 70-hour power reserves versus the Luna’s 38 hours and carry COSC certification.

The T607-9 runs at 28,800 vibrations per hour (4 Hz), delivers a 38-hour power reserve and carries Sellita’s own chronometer-grade rating of −4/+6 seconds per day. That is not a COSC certificate — the movement is not submitted to the Swiss testing body — but Sellita guarantees COSC-equivalent accuracy under its own grading protocol. In practice, forum owners report settling around −2/+4 seconds per day after a few weeks of wear.

The moon phase itself uses a standard 59-tooth gear, which drifts by approximately one day every 2 years and 7 months. You correct it via the crown — pull to the first position and advance the moon disc. High-end astronomical moon phases from brands like A. Lange & Söhne and Patek Philippe achieve accuracy within one day per 122 years, but those movements start at roughly ten times the Luna’s price. At $3,000, the 59-tooth standard is universal.

The Jubilee-Style Bracelet

Tudor pairs the Luna with a seven-link stainless steel bracelet that borrows heavily from Rolex’s Jubilee design. The links alternate between brushed centre links and polished outer links, giving the bracelet a dressy shimmer that suits the moon phase dial. At 39 mm on this bracelet, the Luna wears lighter and more refined than any Tudor North Flag or Pelagos.

The clasp is a two-part folding design with the Tudor name etched into the underside. It does not include push-buttons or a micro-adjustment system. That is the Luna’s most common criticism in owner forums: on a warm day, the bracelet can feel slightly too tight, and there is no half-link solution or quick-adjust built into the clasp. The alternative is to have your authorised dealer remove or add a link, which is a permanent adjustment rather than the tool-free convenience found on the Pelagos’s spring-loaded clasp.

Tudor does not currently offer the Luna on a leather strap from the factory, though the 20 mm lug width accepts aftermarket straps without modification. A dark brown or navy alligator strap can push the watch further into dress territory, while a canvas NATO — if you can forgive the tonal mismatch — makes it more casual.

How the Luna Compares

The sub-$3,500 moon phase segment has more options than most buyers expect. Here is how the Luna stacks up against the models you are most likely cross-shopping.

Pricing and Early Resale Data

All three Tudor 1926 Luna references retail at $3,000 USD. That is roughly $500 more than the standard 1926 39 mm time-and-date model on the same bracelet, making the moon phase complication a relatively modest upcharge. In the UK, the blue dial is listed at £2,655 (inclusive of VAT), and the Euro-zone retail is approximately €2,720.

On the secondary market, the Luna has been trading below retail since its first months. Pre-owned and unworn examples have appeared on dealer and forum listings between $1,950 and $2,700, with the blue dial consistently commanding the highest ask prices. The champagne dial — perhaps because of the Jay Chou association and its niche appeal — has traded at the lowest end of that range.

That depreciation pattern is typical for Tudor’s non-sport models. The watches that hold their value best in Tudor’s lineup are the Black Bay and Pelagos ranges, where limited production and strong brand association with Rolex support secondary market pricing. The 1926 collection, by contrast, is widely available at authorised dealers and does not generate waitlist demand.

That is not a criticism — it means you can walk into an AD, try the watch on, and leave wearing it the same day. And if you are buying pre-owned, the below-retail asking prices mean you can pick up a barely-worn Luna for $300–$500 less than the sticker.
