A high quality unpadded strap can look great. An average/poor unpadded strap tends to curl on the edges and look funny.

Most padded straps will look better under a wider range of conditions, but some combinations look better flat.  @OscarKlosoff -- yes some thick padding looks off for a given watch but the question didn't distinguish between levels of padding. 

Just my opinion and taste. There can never be a right or wrong answer. 

I'm here to be the first on Watchcrunch to tell you that watches were in fact disposable back in the day and barely different from current views on smartwatches. 

In reporting from older people/relatives who wore mechanical watches from the pre-quartz era: Yes, watches were often disposable. One of my relatives used to routinely smash her watch or get it wet, and hers died every few years at most. She had a box full of broken mechanical watches, including high quality gift watches received on memorable occasions. With the arrival of quartz, daily use watches became more durable and long lived. 

I myself have purchased digital watches as disposable items, with no intention of ever replacing the battery. This included what are now considered classic Casio models. When digital watches first came out in the 1970s they were pricy cutting-edge tech, but in the 1980s they became disposable commodities and got better every year. Casio crammed all sorts of new functions into those watches, including world time, alarms, primitive games, lights, radio atomic time, and more. So these WERE the smartwatches of the day, just awkward and weak ones versus Apple Watches and others. 

In sum, I think of watches falling into either a (1) functional / tool group versus a (2) fashion / art / gadget / collectable group. When any generation of watch tech is heavily used it'll break. This includes hand-wind, automatic, quartz, or smartwatches. The least reliable are probably mechanical chronographs -- certainly if used for abusive sports such as diving, skiing, cycling, shooting, or simple manual labor. One can look at the amazing craftsmanship of a Swiss chrono...as it fails to function after a single impact or dunk underwater...and then pay more than the price of a smartwatch to have it repaired. The Apple Watch has a water purge feature and is fully capable of surviving many abusive sports, even if not close to a G-Shock for diving. 

All hobby items go through "new tech" to "old junk" and then back to "nostalgic collectable" phases. Smartwatches haven't yet reached the nostalgia phase. They will in a few decades. 

Either the non-dominant wrist to avoid damage or the wrist that best keeps out of the way. Ever wear a bracelet watch on your right wrist while using a computer mouse? You get a hard, cold, bumpy, and scratched wrist-rest for free. 

Older hobby forums (e.g., 10 years) tend to be dominated by a relative handful of regulars. They combine experience with "if it ain't broke" rigidity. Innocent new users get crushed for asking naïve new user questions. Some cranky regulars imagine trolls in every other post, when they themselves actually cause more trouble. But with experience and high post counts, these long-term users dominate the environment. Furthermore, large sites attract industry people who tend to avoid open discussions and focus on positive brand propaganda or marketing. 

Once people start to notice these patterns, active hobbyists (topic-oriented) break off and form new sites (e.g., this one) to get away from that atmosphere. Many people want a fresh start. This pattern applies to all kinds of hobbies.  

Anything with orange and black will end up as a Halloween theme. No way to avoid that. Of these option the white version is least like Halloween, but I still wouldn't buy it. 

Rolex/Tudor buy large quantities of raw 316L stainless steel sheets and run it through automated machines. Robotic/CNC equipment mills the cases and bracelets down to near-final dimensions, with a few humans involved with assembly and polishing.

Those machines could be located in Switzerland or China. It's the same basic cost either way. Swiss builders are selling luxury items and likely have massive profit margins. Even if 100% Swiss, don't ask why Tudor is cheap and instead ask why very similar Rolexes are so expensive. 

Business context, yes it fits. Smartwatches are tools for the workday. Business suits are as much about keeping warm in excessively air-conditioned offices as dressing up. Visit any technology-friendly organization, conference, or event and you'll see more smartwatches than anything else. Attendees also take notes on notebooks or tablets.

Weddings and formal parties, no it doesn't fit. Watches are jewelry and fashion items, so they should match other fashionable clothing items. Pair dress watches with cufflinks, tie clips, eye glasses, neckties, leather belts and shoes, etc.
