Dial and Bezel Features
The watch features a prominent tachymeter bezel with a distinct red and blue color scheme. The dial surface is black and includes applied hour markers, with a sub-dial positioned at the bottom of the dial for chronograph functions. Hands are present for hours, minutes, and the chronograph center-seconds. A rectangular window at the three o'clock position displays the day of the week, shown in Japanese kanji, alongside the numerical date. Printed text on the dial confirms the brand as 'Seiko', includes the 'Speed-Timer' model designation, and notes 'Sports' and 'Water 70 Proof' specifications, with a '21J' indicator for the movement jewel count.
Cataloguing and Sale Context
The source clarifies that the provided information is a summary rather than a formal catalogue entry, and it emphasizes that the data is limited to the current pre-sale status. The listing serves to facilitate contact between the seller and interested parties. There is no assertion of authenticity or exhaustive provenance provided in the documentation, and the user is directed to engage with the support team for all inquiries regarding the object's history and mechanics.
Case and Bracelet Construction
The timepiece is housed in a stainless steel case with a polished and brushed finish. The right side of the case integrates the crown and two pushers for the chronograph operation. The watch is attached to a stainless steel bracelet, which appears to be of an integrated design featuring multiple rectangular links. The case back and internal technical components remain undocumented by the source. Consequently, exact measurements such as case diameter and depth are not confirmed, and the source specifies that all technical data is subject to direct inquiry by potential purchasers.
