Seiko 5 Automatic Day-Date, calibre 7S26, 21 jewels, reference 7S26-02W0, running – navy dial with luminous markers and Arabic numerals at 12, 6 and 9, day and date at 3 o'clock, crown at 4, display caseback, on its original Seiko steel bracelet. PLEASE NOTE: the number 1110921 at the start of the seller's own title is not engraved anywhere on the watch – it is the seller's stock number. The serial number on the caseback ring reads 3D2215, with the first digit partly obscured by the edge of the ring in the photographs, so the year of manufacture given below is an estimate. The code printed at the foot of the dial, 7S26-09A4, differs from the case code 7S26-02W0 engraved on the caseback: on Seiko watches the dial code identifies the dial and the case code identifies the case, so the two are not expected to match and the difference is not a sign of a replaced part. The caseback is marked WATER RESISTANT with no depth or bar rating, and the gaskets have never been tested or replaced, so the watch is not water resistant and must be kept away from water. The display caseback and the front crystal are not marked as sapphire anywhere, so no claim is made about their material. The case diameter has been measured with a caliper at 38 mm. The lug width has not yet been measured and is given below as an approximation. Overview A compact Seiko 5 day-date automatic in stainless steel on the 7S26 calibre, with the crown at 4 o'clock and a display caseback showing the signed rotor. The dial is a matte navy – measured off the photographs at a hue of about 213 degrees with a brightness of around 30 per cent, a deep navy rather than a bright blue – carrying the applied SEIKO and shield-shaped 5 below 12 and AUTOMATIC over 21 JEWELS above 6. The hours are marked by white luminous Arabic numerals at 12, 6 and 9 and applied bar markers with luminous strips at the other positions, with a minute track and five-minute numerals round the edge. The dauphine hour and minute hands carry luminous inlays and the white seconds hand has a yellow tip and a luminous dot on its counterweight. The day and the date share a window at 3 o'clock, the day in English with Sunday in red. The polished bezel is fixed, and the bracelet is the original Seiko three-row oyster-style bracelet with the SEIKO and 5 shield on the clasp.

The rotor is marked SEIKO TIME CORP and TWENTY-ONE 21 JEWELS; the movement is clean, with no rust, discolouration or debris visible. The 7S26 has no hand winding; it is wound by the rotor as the watch is worn or moved. - Date of manufacture: estimated at December 2013 from the serial number under Seiko's dating convention, consistent with the production period of this reference - Case: stainless steel with a fixed polished bezel, an unsigned crown at 4 o'clock and a display caseback. The caseback ring is engraved SEIKO / WATER RESISTANT / ST.STEEL 7S26-02W0 / A4 in a box / KY, with the serial number. No sticker.

The material is not marked anywhere – see the note above. - Dial: navy with a matte to very lightly satin finish, no sunray. Measured off the photographs with the white background in the same frame used to correct the white balance, the dial reads at a hue of 212 to 214 degrees with a saturation of 39 to 53 per cent and a brightness of 29 to 35 per cent, so a deep navy. - Dial printing and fittings: applied SEIKO and shield-shaped 5 below 12; AUTOMATIC and 21 JEWELS printed above 6; the dial code 7S26-09A4 R 2 at the foot of the dial. There is no water-resistance marking on the dial. - Markers: white luminous Arabic numerals at 12, 6 and 9, applied bar markers with luminous strips at the other hours, and a printed minute track with five-minute numerals at the outer edge - Hands: dauphine hour and minute hands with luminous inlays, and a white seconds hand with a yellow tip and a luminous dot on the counterweight. The luminous material is a pale green with no significant ageing; whether it still glows has not been tested. - Day and date: shared window at 3 o'clock, white discs with black numerals, the day in English with Sunday printed in red. The language shown on the other side of the day disc has not been checked. - Water resistance: marked WATER RESISTANT with no rating, and the gaskets have not been tested – see the note above - Bracelet: original Seiko stainless steel bracelet, three-row oyster style, with SEIKO and the 5 shield on the clasp cover and STAINLESS STEEL on the inside. No other maker's name appears anywhere on it. Push-button folding clasp with four micro-adjustment holes, and arrow-marked removable links on both sides. No spare links are included. - Lug width: approximately 20 mm, estimated from the photographs – to be confirmed by measurement - Wearable size: as linked the bracelet fits a wrist of approximately 170 to 175 mm, taken from the graduated cone in the photographs; the four micro-adjustment holes allow a few millimetres either way. No spare links are included, so it cannot be lengthened beyond this. - Weight: 98.12 g - Included accessories: none Condition Very good, with minor signs of wear. - Dial: very good. No stains, no crazing, no discolouration and no lifting of the markers were found under magnification, and the printing is sharp. The luminous numerals, strips and inlays are complete. - Markers: all present, firmly seated and free of corrosion. - Crystal: no scratches, chips or cracks were found. A faint wavy line that appears beside the 5-minute marker in some of the photographs was checked on the watch itself and is a reflection, not a scratch. - Hands: all three straight and clean, with no corrosion. - Case and bezel: light hairlines on the polished bezel and the case flanks from normal wear. No dents and no distortion. - Display caseback: the glass is clear with no scratches found, and the engraving on the ring is legible. - Movement, seen through the display back: clean, with no rust, no damage and nothing missing. - Crown: intact and correctly seated, with no chips or deformation. - Corrosion: no rust and no green corrosion were found anywhere on the watch. - Bracelet and clasp: no broken or missing links and no rust. The clasp cover carries numerous fine hairlines from normal wear, and there are light scratches on the polished centre links. The clasp closes and latches correctly. Stretch could not be assessed from the photographs. Working order The watch is running. The seconds hand was checked against the timestamps of four photographs spanning 25.7 seconds: over that interval it advanced the equivalent of 24.8 seconds, a difference of under a second, which is within the accuracy of reading a hand position from a photograph, and there is no point at which it stopped. The day and the date are displayed correctly. The power reserve, the automatic winding by the rotor, the day and date changeover, the timekeeping accuracy and the water resistance have not been tested with equipment, and the movement has not been serviced. Please consider this a used mechanical watch that may require servicing at some point. Included Watch and bracelet only. No box, papers, warranty card, spare links or other accessories.
