My first Seiko automatic is here, and I’m still smiling every time I look down at my wrist. There’s something special about wearing a watch powered by a mechanical movement rather than a battery. I haven’t confirmed the exact reference, so this is a celebration of the first automatic—not a claim about a particular Seiko model.
Why a first automatic feels different
An automatic watch turns ordinary moments into small reminders of how it works: the movement of your wrist helps wind its mainspring, and the stored energy keeps the watch running. That mechanical connection is a big part of the appeal. It makes this first Seiko feel like more than another thing to wear.

Seiko makes watches across several collections, and “Seiko automatic” alone doesn’t identify a specific model. A clear dial photo or the reference number on the case back is needed before attaching collection names or specifications to this watch.

Part of the fun is getting to know the watch through everyday wear: how it sits on the wrist, how the dial looks in different light, and how its timekeeping fits into my routine. The useful details—such as winding, setting the calendar, water resistance, and strap sizing—depend on the confirmed model, so I’ll follow its own product information and instructions rather than guess.

- Power reserve: approximately 41 hours
- 21,600 vibrations per hour
For a sense of how much models can differ, Seiko’s SRPE55 Seiko 5 Sports is one documented example, not an identification of this watch. Seiko lists that model with a 4R36 movement, 40.0 mm case diameter, 44.6 mm lug-to-lug length, 11.5 mm thickness, 20 mm lug width, and 10-bar water resistance. Those measurements and specifications belong to the SRPE55 only.
A small note for new automatic-watch owners
If this is your first automatic too, keep the care simple: find the official instructions for your exact reference and use them for operating guidance. Seiko’s 4R35 / 4R36 instructions describe those movements specifically. They state that the 4R36 has automatic winding, can also be wound manually, and has an approximately 41-hour power reserve; that information applies only if a watch actually uses a 4R36. The manual also notes that strong external magnetism can affect timekeeping and that accuracy varies with wearing and use conditions.
Rank #2
- STUNNING BLUE DIAL: this automatic men's watch features a deep blue, pressed pattern and gloss finish surrounded by a stainless steel watch case
- AUTOMATIC: these self-winding, automatic men's watches are powered by your movement, with a power reserve of 41 hours
- STAINLESS STEEL: features a durable stainless steel watch case and bracelet with see through caseback
- WATER-RESISTANT: these men's wrist watches are water-resistant down to 50 meters
- 4R35 CALIBER: equipped with the reliable caliber 4R35 automatic movement, this accurate men's watch keeps precise time
Water resistance is not a safe-swimming guarantee based on the word “automatic.” Check the confirmed model’s stated rating and instructions before exposing it to water, and use a watchmaker for questions that the documentation does not answer.
The best part is that it’s mine
The exact reference can wait until I’ve checked it properly. For now, the important thing is that I’ve crossed off a personal milestone: my first automatic watch, and a Seiko I’m excited to wear.
