Roger W. Smith makes fewer than ten watches a year on the Isle of Man, and the Series 4 is the one that shows everything he knows. White enamel dial, rose gold case, movement finished and assembled entirely by hand in a tradition that runs directly back to George Daniels. If you want a living document of English watchmaking at its highest point, this is it.
Smith trained under George Daniels in the 1990s and inherited not just Daniels's techniques but his commitment to making watches from scratch rather than finishing bought-in ebauches. The Series 4 was introduced in 2006 as Smith's definitive expression of that philosophy: every component of the Caliber Series 4 movement is produced in his own workshop, including the escapement. The white enamel dial and rose gold case are not stylistic choices so much as a direct continuation of the pocket watch aesthetic Daniels built his reputation on.
Production has remained deliberately tiny, typically under ten pieces annually, and wait times run to years. The horological community places the Series 4 alongside Daniels's own work as proof that English fine watchmaking did not die in the twentieth century.
The secondary market for the Series 4 is thin and illiquid. Prices vary considerably depending on whether a piece comes with full documentation, and without provenance the value case weakens quickly. Buyers occasionally encounter examples described as Series 4 that are actually earlier Smith references; confirm the specific caliber designation and case number with Smith's workshop before purchasing.
Because production is so small, there is essentially no established grey-market price history to calibrate against, which makes it harder to know whether a given asking price is fair. The market skews toward serious collectors and institutional buyers, so patience is required on both ends of a transaction.
New Series 4 pieces are allocated directly by Roger W. Smith's workshop and are not sold through retailers, so acquiring one new means joining a waitlist and building a direct relationship with the maker. Secondary market examples appear occasionally through specialist auction houses, notably Phillips and Bonhams, and at a handful of independent dealers who focus on haute horlogerie.
Prices on the secondary market have generally tracked upward over the past decade but remain below what a comparable Daniels pocket watch commands, which most informed buyers view as a rational pricing gap that may close over time.
Service should go exclusively to Roger W. Smith's workshop on the Isle of Man, the only facility with full access to the Caliber Series 4 specifications and proprietary tooling. The movement's hand-produced components are not interchangeable with parts from any supplier, so independent servicing carries real risk of damage or irreversible alteration.
Contact the workshop directly to arrange service; intervals are typically longer than mass-produced calibers given the quality of the finishing and the materials used.

The Series 4 uses an English lever escapement rather than co-axial; the English lever architecture through the caseback is the correct escapement for this earlier RWS platform.
| Area | What to check | What is correct | Red flag |
|---|---|---|---|
| movement | English lever escapement architecture | English lever escapement visible through caseback; correct for Series 4 | Co-axial wheel present; would indicate a Series 1/2/3 movement in a Series 4 case |
| movement | In-house hand-wound architecture | Hand-wound movement with no rotor | Automatic rotor present; wrong movement for Series 4 |
| caseback | Roger W. Smith serial and Series 4 designation | Serial and Series 4 designation correctly engraved | Missing or incorrect engravings; non-genuine caseback |
| movement | Smith-level movement finishing | Hand-done finishing consistent with RWS workshop standards under a loupe | Machine-regular finishing; non-genuine movement |
