I hand the chance recently to photograph two great Rolex Big crowns the Rolex 5510 and the Rolex 6538 4 line. I must admit this 6538 is the best example I have ever seen and next to my 5510 you can see clearly the resemblance. 




Rolex 5510 vs Rolex 6538 - Rolex big crowns.


The 5510 was produced to replace the 6538 moving from the 1030 movement the 1530 bringing an end to the caliber 1030. While the Rolex 6538 was produced for several years the 5510 had a very short life with estimates of 400-600 units produced late 1958. The 5512 replaced the 5510 in 1959. The most remarkable difference, other than the movement as the share the same crystal, 8mm crown and bezel/insert, is the case. The case is much thicker to house the 1030 movement in addition the lug ends have a much more pronounced curve which is clearly visible side by side. This was the first time that i really noticed the shape of the curved lugs observing the two watches in an unpolished condition or at least as vlose to the original shape. 

No major revelations but i thought it was nice to share.

About the Rolex Oyster Perpetual Ref. 1030

The Rolex Oyster Perpetual reference 1030 represents an early iteration of the self-winding Oyster Perpetual line, a foundational model for the brand. This reference is distinguished by its automatic movement, housed within the robust Oyster case, which established the core principles of water resistance and automatic winding that became hallmarks of Rolex watches. It was part of the broader Oyster Perpetual family that emphasized reliability and everyday wearability.

This reference typically features a stainless steel Oyster case, housing the Rolex Caliber 1030, an automatic movement. The case diameter is commonly found around 34mm, a standard size for men's watches of its era. The watch is fitted with a domed acrylic crystal, contributing to its vintage aesthetic. The Caliber 1030 movement provides a power reserve suitable for daily use.

For collectors, the reference 1030 is significant as it showcases Rolex's commitment to developing durable and precise automatic timepieces. It appeals to those interested in the evolution of the Oyster Perpetual series and the early application of Rolex's self-winding technology. Variants exist with different dial configurations and hour markers, offering diversity within the reference.

Not everyday we see these 2, especially the 5510. The 6538 4 lines is superb, too!

I like these original inserts with the red triangle a lot. Thanks for sharing, Bill. Best, Nicolas
