The RGM Model 207-EB pairs a compact 35 mm polished-steel case with a blue rosette guilloché dial and a Sellita SW300-1 automatic movement. Fratello Watches reported those specifications and a US$5,950 pre-tax price in its February 26, 2025 hands-on review; that price is dated, not confirmation of what the watch costs today.
What makes the 207-EB’s dial distinctive?
The defining feature is the blue dial’s rosette-pattern guilloché center. Fratello describes the pattern as becoming finer toward the middle, with a separate guilloché ring around it. Circular brushing adds another texture to the dial, while printed Breguet numerals and a printed minute track keep the display legible. A date window sits at 3 o’clock.
Fratello’s review says RGM owns several engine-turning machines and notes the staff’s skill in applying dial patterns. The specific visual point on this model is the rosette’s tightening pattern—not an established claim about rarity or production volume.

How does the 207-EB compare with the 207-E and 207?
Fratello’s February 2025 review offers two useful alternatives to the blue, engine-turned 207-EB: the silver-guilloché 207-E and a non-guilloché Model 207. The reported prices are historical review figures, not current quotes.

| Model | Dial treatment described | Price reported by Fratello, February 26, 2025 |
|---|---|---|
| 207-EB | Blue dial with rosette guilloché center and guilloché ring | US$5,950 before taxes |
| 207-E | Silver guilloché dial | US$2,950 excluding taxes |
| 207 | Non-guilloché; glossy black or sunburst blue pilot dial options described | US$2,950 excluding taxes |
The clearest documented distinctions are dial treatment and the review-reported price gap: the 207-EB was listed US$3,000 above the 207-E and non-guilloché 207 in that review. The source does not establish that the variants share every other specification, nor does it establish current prices, stock, or delivery timing.
What did the review say about the strap?
The 207-EB is described with a brown alligator-leather strap lined with rubber. The Fratello reviewer preferred the look of nubuck, which is an individual aesthetic preference rather than a fit recommendation. With no lug width stated in the review, a specific replacement strap size cannot be confirmed from these details.
Rank #3
- Suitable for NH 35/NH36 watch movement
- Blue luminous effect makes it glow at night or at the dark places.
- High precision machining, stable and reliable, with fine workmanship and exquisite appearance
- Reasonable design makes it easy and convenient to install and remove, and it is a wonderful replacement for broken or old one
- Multiple colors to choose to show your own personality and match your watch
What is the price context?
Fratello reported US$5,950 before taxes for the 207-EB on February 26, 2025. It reported US$2,950 excluding taxes for both the 207-E and the non-guilloché 207. Those are dated figures; the available sources do not confirm current prices or availability. RGM’s March 13, 2025 official blog lists the Fratello article under recent press, corroborating the article-model association but not present-day stock or specifications: RGM Watch Co.’s recent press page.
