Seiko 7A38 A Legacy of Innovation

Design and Features of the Seiko 7A38

The Seiko 7A38 is a classic quartz chronograph wristwatch that was first introduced in 1980. It’s renowned for its sleek design, innovative features, and reliable performance. The 7A38 has become a highly sought-after collector’s item, and its popularity continues to grow.

Design Elements of the Seiko 7A38

The 7A38 boasts a distinctive design that blends functionality and style. The case is typically made of stainless steel, with a variety of finishes available, including polished, brushed, and black PVD coated. The case size ranges from 37mm to 40mm in diameter, making it suitable for a wide range of wrist sizes.

The dial is often characterized by its clean and uncluttered layout. It features large, legible hands and hour markers, making it easy to read the time at a glance. The dial can be found in various colors, including black, white, blue, and silver.

The hands of the 7A38 are typically designed with a minimalist aesthetic. The hour and minute hands are usually slender and pointed, while the chronograph second hand is often longer and thicker, with a contrasting color for easy visibility. The hands are often coated with luminous material for enhanced visibility in low-light conditions.

The bezel is typically a fixed stainless steel bezel, often with a tachymeter scale for measuring speed. The tachymeter scale allows the wearer to calculate speed based on the time it takes for an object to travel a specific distance.

Functionality of the Seiko 7A38

The Seiko 7A38 is a multi-functional chronograph watch that offers a wide range of features.

Chronograph Functionality

The 7A38’s chronograph function allows the wearer to measure elapsed time with precision. The chronograph is activated by pressing the top push button, which starts the chronograph second hand. The bottom push button stops the chronograph, and the middle push button resets the chronograph to zero. The chronograph can measure time up to 12 hours, with a 1/5 second resolution.

Alarm Functionality

The 7A38 also features an alarm function. The alarm can be set to a specific time, and it will sound an audible alert when the set time is reached. The alarm is activated and deactivated using the crown.

Date Functionality

The 7A38 includes a date window, usually located at the 3 o’clock position on the dial. The date window displays the current day of the month. The date is adjusted using the crown.

Movement of the Seiko 7A38

The Seiko 7A38 is powered by a quartz movement, which is known for its accuracy and reliability.

Quartz Crystal

At the heart of the 7A38’s movement is a quartz crystal. The quartz crystal is a small piece of piezoelectric material that vibrates at a precise frequency when an electric current is applied to it. This vibration is the basis for the watch’s timekeeping function.

Oscillator

The quartz crystal is connected to an oscillator, which is an electronic circuit that generates a stable electrical signal based on the vibrations of the crystal. The oscillator ensures that the crystal vibrates at a constant frequency, which is essential for accurate timekeeping.

Motor

The oscillator’s electrical signal is then transmitted to a motor, which drives the watch’s hands. The motor is a small, powerful device that converts the electrical signal into mechanical motion.
