Oysterflex is not a conventional rubber strap: Rolex describes flexible metal blades inside each bracelet section, overmoulded with black elastomer. This guide maps the principal references identified here and rates them on disclosed criteria—not resale predictions or unverified wrist impressions. It is not an exhaustive catalog of every dial, gem-set configuration or production suffix.
What Oysterflex is—and what it is not
Rolex describes the Daytona Oysterflex as “made up of two flexible curved metal blades – one in each bracelet section – overmoulded with high-performance black elastomer.” The construction gives the bracelet an elastomer exterior with metal structure beneath it; calling it simply a rubber strap leaves out a defining part of the design. On the Daytona, Rolex also specifies inner cushions, an Oysterlock safety clasp and Glidelock adjustment. These are manufacturer specifications, not independent comfort or durability test results. Rolex Daytona reference 126515LN
For Yacht-Master models, Rolex likewise describes two overmoulded metal blades, an Oysterlock clasp and a patented Glidelock extension mechanism. Rolex says its Yacht-Master Glidelock has six notches of approximately 2.5 mm each, providing about 15 mm of adjustment. Its Daytona collection page also describes up to about 15 mm of Glidelock adjustment. Rolex Yacht-Master collection specifications · Rolex Cosmograph Daytona collection specifications
Principal Rolex Oysterflex reference map
The table covers principal references surfaced in the available reference guide, not every dial or gem-set suffix. Rolex’s collection pages establish the model families and Oysterflex construction; the detailed reference mapping and historical transitions below rely in part on Bob’s Watches, a secondary source. Treat “current” as that guide’s lineup description rather than a guarantee of present catalog status or stock.

Bob’s Watches Oysterflex reference guide
How these watches are rated
These ratings assess only characteristics supported by the reference map and manufacturer specifications: case-size choice, metal options, the complication or role identified for the family, and confidence in the reference evidence. They do not rate personal comfort, durability, scarcity or investment value. A reference supported only by the secondary guide receives a lower confidence rating than one independently confirmed by Rolex.
| Family or example | Size and metal choice | Function or distinction | Reference confidence | Rating |
|---|---|---|---|---|
| Yacht-Master 37, 268655 | 37 mm Everose; smallest listed size | Yacht-Master model family | Principal reference surfaced in secondary guide; no exact product specification cited here. | 3.5/5 — strongest listed choice for the smallest case, with less source confirmation. |
| Yacht-Master 40, 116655 and 126655 | 40 mm Everose | Guide identifies the first Oysterflex Rolex and its later generation. | Reference sequence from secondary guide; Rolex confirms the model family and construction. | 4/5 — clear historical significance and a later reference, but detailed transitions rest on secondary sourcing. |
| Yacht-Master 42, 226659 and 226658 | 42 mm in white or yellow gold | Two documented metal directions within the listed family. | Reference and metal mapping from secondary guide; Rolex confirms selected 42 mm gold Yacht-Master Oysterflex variants. | 4/5 — broadest metal contrast among the listed Yacht-Master sizes; reference specifics merit individual verification. |
| Daytona 1165xxLN family | Gold options: Everose, yellow and white; size not stated in the cited reference guide. | Daytona chronograph family. | Earlier reference family from secondary guide; Rolex confirms Daytona Oysterflex as a collection configuration. | 3.5/5 — useful historic range, with fewer exact specifications confirmed here. |
| Daytona 126515LN | 40 mm Everose | Chronograph; Rolex specifies calibre 4131. | Exact model, construction and specifications confirmed by Rolex. | 4.5/5 — highest evidence confidence in this comparison and the most fully specified example. |
| Daytona 126518LN and 126519LN | Yellow gold and white gold; size not stated in the cited reference guide. | Daytona chronograph family. | Later-family mapping from secondary guide; exact listed specifications are not established here. | 3.5/5 — useful metal alternatives, but less exact-source support than 126515LN. |
| Sky-Dweller 326235, 336235 and 336238 | Everose and yellow gold; case size not stated in the cited reference guide. | Sky-Dweller family; exact complication specifications for these references are not established by the cited pages here. | Reference and generation claims from secondary guide; current catalog status not independently confirmed. | 3/5 — distinctive family inclusion, but the least fully substantiated reference details in this comparison. |
A fully specified example: Daytona 126515LN
Rolex’s US product page identifies reference 126515LN as a 40 mm Everose-gold Cosmograph Daytona with an Oysterflex bracelet. Rolex lists calibre 4131, an approximately 72-hour power reserve, water resistance to 100 metres (330 feet), and precision of −2/+2 seconds per day after casing. These are Rolex’s stated specifications, not independent test results. Rolex US Daytona 126515LN product page

What to verify when identifying a specific watch
- Match the complete reference, including its suffix, to the exact metal, dial and configuration; a family-level reference list does not prove every variant.
- For unusual gem-set, stone-dial or special-color versions, seek model-specific documentation rather than relying on a general Oysterflex list.
- Separate a model’s catalog status from a retailer’s inventory: the secondary guide’s “current” labels do not establish availability today.
- For an exact specification or sale price, use the product page for the relevant market and reference. The detailed 126515LN figures above apply to Rolex’s US page.
Product prices and availability are accurate as of the date/time indicated and are subject to change. Any price and availability information displayed on Amazon at the time of purchase will apply.
