Rado 11006 Manchester Sapphire reference guide
Rado reference 11006 is a 1970s automatic whose value rests on the dial, faceted crystal and coherent Manchester Sapphire configuration.

Browse 27 live Rado auctionsThe Rado 11006 belongs to the bold 1970s end of the catalogue: an automatic steel watch built around a cushion-shaped case, forceful dial furniture and the moving anchor. Manchester Sapphire examples add a faceted sapphire crystal that changes the dial as the light moves.
The reference is less tidy than its name suggests. Watches carrying 11006 have surfaced as Manchester, Manchester Sapphire and Trident 300, with different dial textures, case measurements and automatic calibers. Buy the configuration, not the number alone.

The model landscape
The Manchester Sapphire is the version to want when the faceted crystal, silver sunburst dial and red date display remain coherent. The crystal gives the watch its optical architecture, while applied faceted indices and black dial printing keep the display legible beneath it. A blue Manchester uses vertical brushing instead, and the effect is flatter but more saturated.
Reference 11006 also occurs on the Trident 300. That watch has a silver dial cut with deep radial texture and a tonneau-shaped steel case, rather than simply being another dial colour of the Manchester Sapphire. Movements also differ: handled examples contain caliber 2797 or ETA caliber 2789, both automatic and listed with 25 jewels. A mismatched model name is therefore not proof of a franken watch, but every component must agree with one known configuration.
On the wrist
Manchester examples measure 35 mm or 36 mm excluding the crown, and the cushion geometry gives them more visual weight than a round watch of equal width. The faceted crystal adds depth above the dial, so the Manchester Sapphire feels architectural rather than thin and discreet. Its silver sunburst finish works under a cuff, although the angular crystal is the point of the watch and deserves daylight.
The Trident 300 measures 33 mm excluding the crown. Its tonneau case and radial dial texture concentrate the design into a smaller footprint, making it the more compact 11006 configuration. Between a clean Manchester Sapphire and a compromised larger example, take the cleaner dial and crystal - one millimetre cannot recover damaged optical surfaces.
What goes wrong
The worst fault is a refinished dial, because the sunburst or vertical brushing, black text, applied furniture and red date display must still read as one period design. A redial costs more than every ordinary case mark combined. Moisture spotting, staining around the dial edge and oxidation on the hands are easier to accept when localized and honestly described.
Faceted crystals need close attention. Chips and heavy scratches interrupt the reflections that distinguish the Manchester Sapphire, while a replacement of the wrong profile changes the entire watch. Over-polishing softens the cushion-case edges, and deep wear can erase the transition between the top surface and flanks. Replaced crowns and mixed caliber or dial combinations can create a franken 11006 even when every individual part is genuine.
Service history is unknown unless paperwork accompanies the watch, and a timegrapher reading does not establish when it was last serviced. The moving anchor should move freely, but its behavior alone cannot authenticate the dial. Of the examples we have handled, the strongest watches make sense first as complete objects; printing and movement finishing then confirm that initial judgement.
What to check before you buy
- Dial and crystal configuration: A Manchester Sapphire should have a faceted sapphire crystal working with the dial beneath it. Confirm that its profile, silver sunburst finish, applied faceted indices and red date display form a coherent configuration.
- Movement and case pairing: Reference 11006 is known with caliber 2797 and ETA caliber 2789. The caliber alone proves little, so its placement must agree with the model name, dial layout and case shape rather than creating a married or franken watch.
- Trident 300 distinction: A Trident 300 marked 11006 should use the compact tonneau-shaped steel case and silver dial with deep radial texture. Treating that dial and case as interchangeable Manchester parts would ignore a material variant distinction.
- Dial originality: The sunburst or vertically brushed texture should continue naturally beneath the applied furniture, with crisp black printing and no paint covering old damage. A service dial is a genuine replacement and must not be described as the original dial.
- Case and crystal wear: Check the cushion or tonneau case for softened transitions caused by polishing, then inspect the faceted crystal for chips and deep scratches. Neither fault makes the watch false, but both materially change the design and its value.
