Rolex Datejust 31 178240-0037 Super Clone : Steel Smooth Bezel Blue Dial 31mm Overview
The Datejust 178240-0037 is the midsize 31mm steel version of the Rolex Oyster Perpetual Datejust, built here with a smooth domed steel bezel and a blue dial. This super clone follows the 178240 reference with a 31mm stainless steel case, a screw-down Twinlock crown, and the three-link Oyster bracelet for $1,299. Every proportion, the bezel curve, and each bracelet link follow the genuine reference within tight production tolerance.
Case, Crown and Lug Profile — 31mm Stainless Steel Build
The Rolex Datejust 178240-0037 super clone carries a 31mm Oyster case, built on a 904L stainless steel core for accurate weight and corrosion resistance. The case uses fully mirror-polished surfaces across the lugs and flanks, and the midsize diameter gives the 178240-0037 the balanced wrist presence of the classic Datejust 31. The screw-down Twinlock crown at 3 o'clock seals the case for water resistance to 100 meters.
Smooth Domed Stainless Steel Bezel
The smooth domed bezel is a defining feature of this Datejust 178240-0037, finished in mirror-polished stainless steel for an understated face. The smooth bezel contrasts with the fluted bezel of other Datejust 31 references and gives the 178240 a cleaner, more restrained profile. This super clone follows the genuine bezel curve and polish so the watch reads correctly under close inspection.
Sapphire Crystal, Cyclops Lens and Caseback
Scratch-resistant sapphire crystal with anti-reflective coating covers the blue dial and carries a Cyclops magnification lens over the date aperture at 3 o'clock. The Cyclops lens enlarges the date by 2.5 times for quick reading, a signature detail of the Datejust line since 1953. The solid screw-down caseback seals the Caliber 2235 clone movement and supports the 100-meter water resistance rating of the Datejust 31
Blue Dial with Applied Steel Markers
The blue dial of this Datejust 178240-0037 super clone carries a deep blue surface that anchors the versatile identity of the reference. The dial uses applied steel baton hour markers and a date aperture at 3 o'clock framed by a polished steel surround. This super clone matches the marker size, the print placement, and the blue dial tone of the genuine 178240-0037.
Luminous Hands and Hour Markers
The Datejust 178240-0037 carries applied steel baton hour markers and baton-style hands filled with luminous material for low-light legibility. The luminous fill gives a clear time reading in dim conditions while keeping the midsize proportions of the reference. The central hour, minute, and seconds hands follow the genuine reference in shape and length, and the markers match the placement of the authentic 178240-0037.
Logo, Text and Symmetry
The applied Rolex coronet sits at 12 o'clock, with "Rolex Oyster Perpetual Datejust" printed across the blue dial in fine text. The print stays crisp against the blue surface, and the line spacing follows the genuine 178240-0037 layout. The blue dial, the smooth steel bezel, and the polished steel case give the 178240 a clean, balanced face that suits both daily wear and dressed occasions.
Swiss-Grade Caliber 2235 Clone Movement
The Rolex Datejust 178240-0037 super clone runs on a Swiss-grade automatic movement engineered to match the genuine Rolex Caliber 2235 in feel, frequency, and autonomy. The Caliber 2235 is the midsize automatic movement Rolex uses in the 31mm Datejust. The movement operates at 28,800 vibrations per hour, winds bidirectionally through a free-rotating rotor, and holds a power reserve of approximately 48 hours for two days off the wrist. The caliber drives the central hours, minutes, seconds, and the date at 3 o'clock.
Accuracy and Daily Performance
Daily deviation holds within -5 to +8 seconds per day after factory regulation, close to the chronometer standard of the genuine Caliber 2235. The smooth sweeping seconds hand and the quiet rotor confirm the Swiss-grade build. The 100-meter water resistance and the screw-down Twinlock crown let the 178240-0037 super clone hold its seal through daily wear, hand washing, and light water contact.

Stainless Steel Oyster Bracelet and Folding Oysterclasp
The Datejust 178240-0037 super clone carries the Oyster bracelet, the three-piece-link design Rolex pairs with the steel smooth-bezel Datejust 31. The bracelet uses a stainless steel finish with brushed outer links and polished center links, tapering smoothly from the lugs toward the wrist. A folding Oysterclasp closes flush against the wrist for a secure hold. The Datejust 31 uses the Oyster bracelet or the Jubilee bracelet and never a President bracelet.
Wrist Feel, Sizing and Comfort
The watch weighs approximately 95 grams on the full Oyster bracelet, giving the balanced wrist presence buyers expect from a midsize steel Datejust 31. The 31mm case slides easily under a cuff and suits both formal and casual wear. The Datejust 178240-0037 sits comfortably on wrists from 5.5 to 7 inches and reads as a clean midsize watch on smaller and medium wrists.

Buyers select the Datejust 178240-0037 for the midsize 31mm case and the clean smooth steel bezel that delivers a restrained, balanced look. The 178274 buyer prefers the fluted white gold bezel for added sparkle on the same 31mm case. The 126200 buyer chooses the larger 36mm steel case. The Datejust 178240-0037 Super Clone gives the midsize 31mm steel Datejust proportions with the understated smooth bezel and the blue dial.
Heritage — The Rolex Datejust and the Midsize 31mm Format
The Rolex Datejust launched in 1945 as the first self-winding wristwatch to show the date in a window on the dial. Rolex paired the model with the Oyster case for water resistance and the Perpetual rotor for automatic winding, which made it the first watch to combine all three features. The Datejust added the Cyclops lens over the date in 1953 to magnify the date for quick reading. Rolex built the Datejust across several case sizes, and the 31mm midsize format gives the model a balanced diameter that suits medium and smaller wrists. The reference 178240 carries the 31mm steel case with the smooth domed bezel and the Caliber 2235 movement, and the dash suffix -0037 marks the blue dial variant. The Datejust 178240-0037 Super Clone carries that long Datejust heritage and the proven midsize engineering onto the wrist.
