Omega Speedmaster 38 Sedna Gold 324.63.38.50.02.003 Guide: Specs and Price

The Omega Speedmaster 38 Co-Axial Chronograph 324.63.38.50.02.003 is a 38 mm automatic chronograph in Omega's Sedna Gold, an 18 ct rose-toned gold alloy, with a silver index dial, an aluminium bezel insert and a leather strap. It is the dress-leaning end of the Speedmaster family: the racing-chronograph layout without the steel bracelet or the 42 mm Moonwatch size. This guide covers the specifications, what Sedna Gold is, how 38 mm wears, how the watch compares with the steel Speedmaster 38, the Moonwatch and the larger Two Counters Racing, dated dealer pricing in 2026 and the checks worth running before you buy. Bizak & Co. sources this reference to order; the Omega Speedmaster collection shows what we can seek.

Omega Speedmaster 38 324.63.38.50.02.003 specifications

Omega revises dimensions, calibre names and warranty terms from time to time, so treat this table as a summary and check the exact figures against the watch's paperwork and Omega's own documentation. If origin labelling matters to you, the Swiss watch industry's Swiss Made rules set out what the label requires.

What is Sedna Gold and will it fade?

Sedna Gold is Omega's name for its own 18 ct rose-toned gold alloy. Omega describes it as a warm red-pink gold that keeps its colour better than a conventional rose gold, which is the reason the alloy exists. The claim comes from Omega rather than from an independent laboratory, so read it as a design intent, not a guarantee. What is not in dispute is the general behaviour of gold cases: the metal itself does not tarnish, it scratches like any precious metal, and wear shows first on the lugs, the case flanks and the edges of the bezel.

If you already own a rose-gold watch from another maker, expect the Sedna Gold to look similar in daylight and slightly redder in warm light. If you are new to gold, the practical point is that a gold case is softer than steel and shows fine hairlines sooner, and that a polish removes metal as well as marks.

Is 38 mm too small for a Speedmaster?

For most wrists, no. The classic Speedmaster Professional Moonwatch is 42 mm, so the 38 mm case reads as a compact chronograph with a smaller footprint, and it suits wrists on the slimmer side and buyers who prefer a watch that slips under a cuff. It is also the natural size for a gold dress chronograph, because gold cases look heavier than steel ones of the same diameter. The honest advice is to try it on: chronographs add pushers and a thicker case, and a 38 mm watch with a tall case can feel different from a 38 mm three-hander.

Two points shape how it wears. First, the leather strap makes it lighter and less sporty than the same head on a bracelet; you feel the gold more than the steel. Second, the aluminium bezel insert and the silver dial keep the face quiet, so the watch reads as a smart casual piece rather than a racing tool.

Speedmaster 38 Sedna Gold vs steel 38 vs Moonwatch vs Two Counters Racing

The comparison that matters most is against the Moonwatch. The Moonwatch is the watch with the history: the Speedmaster line dates to 1957, NASA qualified it for crewed missions in 1965 and Apollo 11 wore it in 1969. The 38 mm Sedna Gold shares the name and the chronograph idea but not the hand-wound movement or the size, so buy it for what it is, a compact gold chronograph, and not as a Moonwatch alternative. We cover the bigger sibling in our Speedmaster Two Counters Racing review.

What does the Co-Axial escapement change?

The Co-Axial escapement was invented by the English watchmaker George Daniels and adopted by Omega for production watches from 1999. Its selling point is reduced sliding friction at the point where the escapement impulses the balance, which in theory means less lubricant dependence and steadier rates between services. In a gold chronograph that matters mostly for service planning: a chronograph is a more complicated movement than a time-only watch, and precious-metal cases raise the cost of any case work.

Practically, treat servicing as a normal ownership cost. Omega and most independent watchmakers suggest a service roughly every several years depending on use, and you should ask for the current interval and the current cost from Omega or an authorised service centre, not from a seller. If you want an independent check on accuracy standards in general, the Swiss Official Chronometer Testing Institute explains what a chronometer certificate does and does not cover; Omega's own Master Chronometer programme is separate, so confirm which certification the specific movement carries.

How do the leather strap and aluminium bezel age?

The two wearing parts are the strap and the bezel insert, and both are replaceable. Leather takes sweat, creases at the buckle end and can separate at the edge within a few years of daily wear; a new strap is a routine expense, and a strap that is stiff and pristine is worth a question about how long it has been stored. Aluminium bezel inserts scratch and fade with sunlight and skin contact more readily than ceramic ones. On a silver-dial gold watch a lightly worn insert is part of the character; a badly nicked one is a negotiating point.

• Strap. Ask whether it is the original Omega strap and buckle and check the stitching at both ends.
• Bezel. Check the insert under a light for nicks near the numerals and for uneven fading.
• Case. Look along the flanks and lugs for hairlines and for softened edges that suggest polishing.

How much is the Omega Speedmaster 38 324.63.38.50.02.003 in 2026?

• Retail. Omega sets its own list prices by market and revises them during the year. A gold Speedmaster 38 sits well above the steel version because of the case metal. Ask an Omega boutique or an authorised dealer for the current figure; we do not quote a retail number that we cannot verify.
• Bizak catalogue ask. On September 29, 2026 Bizak's sourced catalogue listed this brand-new reference at US$19,805, sourced to order. That is a dated observation of our catalogue, not an offer, and the final price is confirmed before you commit.
• Secondary market. Precious-metal Omegas generally change hands below retail once worn, so a full-set brand-new example priced under the boutique figure is not automatically a warning sign, but the paperwork should explain it.

Is a gold Speedmaster 38 a good investment?

Treat it as a watch to wear, not a store of value. Gold Omegas are usually bought for the material and the look, and their prices depend more on the gold content and condition than on collector demand. That differs from a steel Rolex sports watch, where scarcity supports the secondary price. If resale matters, keep the box, warranty card and strap, and ask for a written buy-back or trade estimate before you commit; our sell or trade page explains how that works.

Buying a brand-new Speedmaster 38: what to check

• Paperwork. Full Omega box, warranty card and hangtags. Ask how the warranty card will be dated and documented before you pay.
• Reference match. The reference on the caseback, the papers and the invoice should agree with 324.63.38.50.02.003.
• Chronograph action. Start, stop and reset: the seconds hand should return cleanly to zero and the pushers should feel even.
• Case and bezel. Inspect under good light for display marks on the gold and nicks on the bezel insert.
• Strap and buckle. Check stitching and buckle engraving, and confirm both are Omega parts.
• Price against the band. An offer far below the figures above deserves a question about the source.

Our authentication process describes what we inspect before dispatch; auction houses such as Phillips and Sotheby's publish results for the wider Omega market if you want independent context.

Quick answers

How much is the Omega Speedmaster 38 Sedna Gold 324.63.38.50.02.003?

Bizak's sourced catalogue listed it brand new at US$19,805 on September 29, 2026, sourced to order. Omega's boutique price varies by market, so ask Omega or an authorised dealer for the current retail figure.

What is Sedna Gold?

Sedna Gold is Omega's own 18 ct rose-toned gold alloy, made to keep its warm colour better than ordinary rose gold. Omega makes that claim; it is not an independent test result.

Is the Speedmaster 38 too small?

It is a compact chronograph at 38 mm, smaller than the 42 mm Moonwatch. It suits slimmer wrists and works well as a dress-casual gold watch, but it is worth trying on because chronograph cases add thickness.

What does the Co-Axial escapement do?

It reduces friction at the escapement, which Omega says supports stable timekeeping and less frequent servicing than a conventional lever escapement. Servicing is still a normal ownership cost.

Is this watch in the Speedmaster Moonwatch family?

It carries the Speedmaster name but is a different watch: 38 mm, Co-Axial automatic and in gold on a leather strap. The Moonwatch is the 42 mm hand-wound model with the space-programme history.
