I'm quite a fan of various types of timepieces, each for different reasons. Aside from the obvious utility of watches alone (telling the time), it is very easy (and reasonable) to appreciate the complex engineering of a timepiece.
It's a symbol of the engineering marvels that our species has been able to achieve: tons of tiny, precisely manufactured parts all working in unity to tell you the time of day (and often more) with remarkable accuracy. Aside from this, timepieces can also reflect your interests, your style, and what you value.
I also believe that beautifully designed and engineered timepieces are one of the greatest symbols of fusing aesthetic design and technical engineering to create a masterpiece.
Grand Seiko SBGA413
A fusion of mechanical watchmaking and quartz-level accuracy via the Spring Drive movement.
- Movement: Spring Drive Caliber 9R65
- Accuracy: ±15 sec/month
- Case: Titanium, 40mm
The completely smooth sweep of the seconds hand (via the Spring Drive movement) is a masterpiece of engineering and aesthetically beautiful. Grand Seiko also makes some of the best dials and has some of the best finishing.
Orient Star RE-AU0110N
Orient Star is a very nice watchmaker, serving as Orient's premium, higher tier line of watches.
This model is simple but beautiful. The color of the dial is nice, the steel has very good finishing, and the power reserve indicator (signature of Orient Star) is very practical and adds to the design.
- Movement: Orient F6N43 Automatic
- Power Reserve: ~50 hours
- Case: SUS316L Stainless Steel
Overall a very solid and beautiful timepiece.
Rolex Day-Date 40
One of the most aesthetically beautiful and classically refined watches ever made, in my opinion. The bracelet, sunburst dial, fluted bezel, date cyclops, day indicator, and feel, are all seemingly perfectly designed.
- Ref: 228239
- Material: Platinum
- Bracelet: Presidential
The beautiful, luxurious design of this piece never gets old.
Omega Speedmaster
The iconic 'Moonwatch', first worn on the Moon during NASA's Apollo missions. Beautiful, reliable, and a piece of human history. I believe it's arguably one of the most, if not the most important watch ever produced.
- Type: Chronograph
- Heritage: Apollo Lunar Missions
- Design: Tool-watch
It's impossible to separate this watch from its moon legacy; it's a piece of human history.
Casio EFK-100
A well-engineered, versatile, solid stainless steel Casio with a reliable Japanese automatic movement and beautiful proportions. It is actually Casio's first automatic watch, and hopefully not the last. This watch is also just super good value for money.
- Movement: Automatic (Seiko/Miyota, model-dependant)
- Case: 39mm x 12.5mm
- Crystal: Sapphire
- Water Resistance: 100m
It's really just a solid timepiece for everyday wear and even special occasions. It's a perfect statement that a reliable, beautiful, and solid watch (plus, with a textured dial reminiscent of Grand Seiko) doesn't need to cost tens of thousands to be respected or of high quality.
G-SHOCK GW-M5610
The ultra-reliable, near-indestructible choice, with atomic timekeeping, 200m dive-level water resistance, and tough solar power, as well as several other extremely practical functions such as world time, stopwatch, countdown timer, LED backlight, and more.
- Power: Tough Solar
- Sync: Multi-Band 6 Atomic
- WR: 200 meters
Near-indestructible and automatically time-correcting. If I could keep only one watch, this would probably be it. In many ways, it puts 'luxury' watches to shame.
Casio F91W-1
A foundational, radically honest watch that I think (rightfully) challenges status-first culture. This watch is excellent at what it does, and has several other practical features such as a stopwatch, alarm, day, date, backlight, and more. It's $20 and puts $20,000 watches to shame in many regards.
- Type: Quartz Digital
- Battery: ~7 years
- Weight: 21g
This is often called the 'watch for everyone' and very rightfully so. It is designed for telling the time and it does it better than just about any other watch out there. Not to mention the durability, and 7 year battery life.
