List prices

Both references list the same price on each Rado store below. The catalog band uses the Singapore from-price, S$3,500.00, which sits in S$3–10k. Other DiaStar Original models on those pages have other prices and are not this row. Euro, US dollar, pound, and franc lists are not converted.

Fit on 6–7 in wrists (6.5 in reference)

Fit: Incomplete (lug-to-lug unpublished). Rado lists a 38.0 mm diameter and 11.9 mm thickness. Rado does not label lug-to-lug.

At 11.9 mm thickness, without lug-to-lug, this site’s fit checker stays Incomplete. It does not treat Monochrome’s 45 mm case length as lug-to-lug, and it does not infer tip-to-tip length from the 38.0 mm width.

The flat top of the wrist (usable span) is the width a watch can sit on without its lugs hanging over the edge.

Not published / not checked

• Lug-to-lug. The 45 mm figure is a case length on Monochrome and Watchdle, not a labelled lug-to-lug.
• Water resistance and a jewel count on the Rado spec tables. Those figures are on Monochrome, and on the rose-gold caseback engraving in Monochrome’s press still.
• A beat rate, and an ETA base calibre. Monochrome prints 21,600 vibrations per hour and calls R808 a skeletonised ETA Powermatic 80. The Rado pages name R808 and do not print those lines. Watchdle repeats them and lists Monochrome as its source.
• A piece limit. The Rado pages and the press text do not print one.
• Reference numbers on the press page. That text describes the yellow-gold and rose-gold Ceramos bezels and does not print R12166159 or R12159309.
• Where EasyClip is written. It is in the product-page autumn paragraph and on the press page, not in the spec table.
• German pages label the 11.9 mm thickness as Höhe. Product pages call the bezel brushing brossé soleil (sunburst brushed).
• Watchdle’s line that both references have a brown rubber strap. Rado lists black for R12166159 and brown for R12159309.
• These two references on All Watches, Vincent Watch, or Gnomon product pages. The authorised dealers guide lists Rado at those shops. Those pages were not opened for this pair.
• A direct download from www.rado.com or press.rado.com. Both hosts timed out on 28 October 2026 (HTTP/2 stream error on www.rado.com). R12159309 on this page is the product PNG named on the Rado page. R12166159 is a JPEG of dia_star_original_skeleton_r12166159_sld_web.png; the full PNG timed out. The pair photo is the press still Monochrome published.

• The same pages name automatic calibre R808, an 80-hour power reserve, the line “Movement tested in 5 position”, a Nivachron hairspring (an antimagnetic balance spring), a sapphire caseback, and a five-year warranty.
• Rado Singapore lists both references at S$3,500.00, VAT included. Rado Germany lists €2,600.00. Rado US lists US$2,700.00.

Cons / gaps (from published facts)

• Without a labelled lug-to-lug, fit stays Incomplete.
• Monochrome’s 45 mm length is not on the Rado pages and is not labelled lug-to-lug.
• Water resistance and jewel count are not on the Rado spec tables. Monochrome prints 100 metres and 25 jewels.
• Watchdle says both straps are brown. Rado’s colour lines are black for R12166159 and brown for R12159309.
