Seiko F033-4000

Golden Digital Saturday!

The F033 is one early simple dress watch, with an outstanding design on the display. By using a rough yet reflective surface as the back panel for the LCD, external light can be reflected in different angles from it, to enhance the contrast of the display for easy reading. This works pretty well even in a dimmer situation. Obviously, it is not really needed for those models equipped with built-in light, and most F models are not light bulb equipped.

【數碼跳字星期六】液晶體顯示大家都見過,不同多說。但如何能在沒有利用額外電力的情況下,把顯示的對比度提高,令顯示更清晰?早在70年代下旬,廠商便研究出一方案,就是把液晶顯示背後一般採用的銀灰色平面背板,改為一塊非平滑的反光背板,作用是能採集不同角度的外來光,從內透過液晶層反射至錶外,讓用者從不同角度看液晶顯示時,都會比一般顯示相對光亮、清晰,有如附有背光的效果。此設計多用在沒有內置光源的型號,可是,這技術未能持續。其中兩個原因是大部份別的型號均設有內置燈;和新發展的全屏背光裝置,要求半透明的背板,也不能採用此設計。從此多反射背板這設計便隨即被淘汰,再沒有被採用,成為科技歷史。

相中F033型號,1979年生產,已接近40年錶齡,屬當時普遍的鍍金行政錶款,附原裝雙截鍍金錶帶。只有一個控制按鈕,切換時間和日曆顯示,簡單、無花巧。
