And the two watches that grabbed my eye and no less than on the grey marker appear to be in the identical value range had been the Tudor Pepsi in steel and the omega moon watch.
Stainless Steel 904l Composition
Rolex has been known to send steel again when it doesn’t meet their exacting specs. After casting and inspection, the steel is then re-melted in a vacuum to purify it and get rid of any inclusions that would diminish its corrosion resistance and result in problems in sprucing. Aftermarket additions void the warranty of recent and used Rolex watches offered by Rolex S.A. or at Rolex is underneath no obligation to guarantee-service watches offered by Beckertime via its service areas.

Rolex utilizes 904L with the greatest of high quality management. Once obtained from Rolex’s steel suppliers, Rolex casts and scans it utilizing SA240 316 Stainless steel plate an electron microscope that is able to detecting the slightest structural or surface defect.
How hard is 904l steel?
1. Rolex. One of the metals developed by Rolex is a material known as Rolesium, a combination of 904L stainless steel superalloy and 950 platinum. Rolesium was used in the 40-mm diameter Oyster case of the Rolex Yacht-Master seen here.
It made sense for them because of the amount of watches they produce, and since they make all their elements in-house. Most other brands get their instances made from exterior suppliers. So despite the fact that 904L metal is better than 316L steel for watches, it’s costlier, requires particular tools and skills, and is overall harder to work with.
- The second most typical grade (after 304); for meals and surgical stainless steel makes use of; Alloy addition of molybdenum prevents specific forms of corrosion.
- They might clearly see that gold and platinum watches didn’t have this corrosion problem, so it wanted fixing.
- SS316 is usually used for constructing nuclear reprocessing plants.
- Most watches which are made from chrome steel are made from this grade.
- In 2003 their entire production line changed to 904L, although it was as early as 1988 that they launched their first 904L metal watch with several versions of the Sea-Dweller.
What watches use 904l steel?
The 316L Stainless steel is far less scratch resistant than the 904L because it has a much higher Rockwell hardness. The main advantage of 904L over 316L is its resistance to acids: “The addition of copper to this grade gives it greatly improved resistance to strong reducing acids, particularly sulphuric acid.”

This has prevented other brands (thus far) from taking advantage of it, and is one thing particular that Rolex has. The benefit is apparent when you deal with any metal Rolex watch.

For the Daytona, this has been the case since the 1990s.
Two-tone Rolex watches have their bezels, winding crowns, and middle bracelet hyperlinks craft from 18-karat gold, whereas the center case and outer links of the bracelet are made from 904L stainless steel. Also,if you purely look at the value from a financial perspective, stainless-steel watches from Rolex are the way in which to go. A natural question is why does not everybody else within the watch industry use 904L steel? A good guess is as a result of it is more expensive and rather more difficult to machine. Rolex had to replace most of their metal working machines and tools to deal with 904L metal.
Harder and extra rust and corrosion-resistant than other steels, this 904L metal can take and maintain a polish extremely nicely. This is why steel Rolex watches look totally different than different metal watches. Rolex calls 904L stainless-steel a “corrosion-resistant superalloy.” 904L differs from 316L due to extra Chromium, Molybdenum, Nickel, and Copper which supplies it improved resistance to acids. 316L is taken into account a harder, more durable, “marine grade” metal, however it doesn’t have luster and acid resistance of 904L.
