FAQ

What lug width does the Rolex Sky-Dweller use?

Rolex Sky-Dweller references use 20 mm or 21 mm or 22 mm depending on the reference and case size, so check yours in the list below. The most common is 22 mm (8 of 15 references with a known width).

Do all Rolex Sky-Dweller references take the same strap?

No. 3 different lug widths appear across the line, often by case size or generation. Check the reference engraved on the case back or between the lugs.

What is the lug width of a Rolex Sky-Dweller?

It depends on the generation and bracelet. The first gold models on an Oyster bracelet measure 21mm, while gold models sold on leather straps measure 22mm. The Rolesor versions took the 22mm width in 2017, and since 2023 the gold Oyster-bracelet models (such as 336935) also use 22mm. Check your exact reference in the index.

Which bracelets can a Sky-Dweller come on?

Rolex offers the three-link Oyster, the five-link Jubilee and the elastomer Oysterflex, all closed by an Oysterclasp. The Jubilee was steel-only until gold versions came in 2024, and the 2023 white gold model is sold only on Oysterflex.

How much can I adjust the bracelet without tools?

The Oyster and Jubilee bracelets have the Easylink comfort extension, which adds about 5mm. The Oysterflex uses Glidelock, with six notches of about 2.5mm for around 15mm of adjustment.

How big does the Sky-Dweller wear?

The case is 42mm wide and 13.8mm thick on current models. Monochrome calls it a fairly big and heavy watch even in steel and suggests it suits wrists above about 17cm best.

Did the 2023 update change the case or straps?

The diameter stayed at 42mm, but lug-to-lug grew by 0.3mm and the gold Oyster-bracelet models widened from 21mm to 22mm lugs, with 0.5mm wider center links.

The story of the Rolex Sky-Dweller

In 2012 Rolex unveiled its first entirely new model in 20 years, a traveller's watch that reads two time zones and a full annual calendar yet needs its date set only once a year, at the end of February.

Chapters

  1. 2023 to today
    Calibre 9002 and wider lugs

    In 2023 the calibre 9002 replaced the 9001, adding the Chronergy escapement, marked on the dial by two small coronets at 6 o'clock. The gold Oyster-bracelet models moved to the 22mm lug width, and in 2024 Rolex fitted a precious-metal Jubilee bracelet to the Sky-Dweller for the first time.

  2. 2020 to 2022
    Rubber for the gold models

    In 2020 the gold Sky-Dweller became available on the Oysterflex, Rolex's elastomer-covered metal-blade bracelet, in yellow gold and Everose. aBlogtoWatch noted the case and movement were unchanged; only the bracelet option was new.

  3. 2017 to 2019
    Steel arrives, price drops

    At Baselworld 2017 Rolex used stainless steel on the Sky-Dweller case for the first time, in two Rolesor references. Ref. 326934 paired a steel case and bracelet with a white gold bezel, lowering the entry price to EUR 13,150. The dials switched to rectangular luminous indexes and longer hands.

  4. 2012 to 2016
    Gold only, and a puzzle

    The Sky-Dweller appeared at Baselworld 2012 in 18k yellow, white or Everose gold, 42mm wide, at around CHF 37,000. It carried Rolex's first annual calendar, called Saros, and the Ring Command bezel. Europa Star noted it was soon eclipsed in the media by the Deepsea that James Cameron took to the Mariana Trench.

  5. 2003 to 2012
    A calendar hidden in patents

    Rolex filed a US patent for a wheel-only annual calendar as early as 2003, followed by a more detailed filing in 2005. In June 2011 it patented a bezel used to select which function the crown would set. Both ideas surfaced together less than a year later.

Worn by

Roger FedererSport2017

Federer says the Sky-Dweller Rolex gave him after his 2017 Australian Open win, engraved with a butterfly, is the watch that holds the most sentimental value to him. British GQ also spotted him in a 326934 at the 2017 Miami Open, and in 2023 he wore a new Sky-Dweller in the Royal Box at Wimbledon.

Michael JordanSport2021

Wore a Sky-Dweller to his NBA Hall of Fame induction in May 2021, and earlier at the Hornets game in Paris in January 2020.

Jack HarlowMusic2022

Wore a blue-dial steel Sky-Dweller, which Robb Report identifies as ref. 326934-0003, to his first Grammys in 2022. In a December 2020 GQ clip he called it the only watch he owned.

Jon RahmSport2023

Paired his green jacket with a Sky-Dweller after winning the 2023 Masters, the same watch he wore after his 2021 U.S. Open win.

Giannis AntetokounmpoSport2021

Wore a Sky-Dweller to the Milwaukee Bucks championship celebration in July 2021.

Kyrie IrvingSport

Chose a yellow gold Sky-Dweller ref. 326138 with a white Roman-numeral dial on a tobacco leather strap to replace his father's lost watch.

Moments

Rumours of an entirely new Rolex collection drove the watch blogs before the doors opened; the Sky-Dweller was the answer, Rolex's first annual calendar.

Rolex named the annual calendar after the Saros, an astronomical cycle, and built it with only four gear wheels and two gear ratios.

After Federer won the 2017 Australian Open, Rolex gave him a Sky-Dweller engraved with a butterfly, because he had spoken of butterflies before the final.

Jon Rahm wore a Sky-Dweller when he won the 2023 Masters at Augusta, the same piece he wore after his 2021 U.S. Open title.

Help

What is lug width?

The gap between the two lugs that hold the strap, in millimetres. A new strap must match it exactly: 20 mm lugs take a 20 mm strap.

Measure it in 30 seconds

  1. Take the strap off, or look at the back of it: many straps print their width.
  2. Measure the inside gap between the lugs with a caliper or a millimetre ruler.
  3. Round to the nearest whole millimetre. Most watches use 18, 20 or 22 mm.

Strap, quick release or system?

Most watches use spring bars, so any strap of the right width fits. Many smartwatches use their own band system instead, such as Apple Watch bands or Garmin QuickFit.
