First Impressions: Complexity Meets Affordability
Unboxing the BENYAR BY-5198 reveals a watch that immediately looks busy—and that's not criticism, it's observation. The dial is packed with subdials, calendar windows, moonphase display, and chronograph functions. The stainless steel bracelet has good weight, the blue sunburst dial catches light beautifully, and the overall presence suggests a watch costing significantly more than $75.
Initial Observations:
- Round case with substantial presence
- Blue sunburst dial (tested version)
- Stainless steel bracelet
- Moonphase display at 6 o'clock
- Multiple calendar windows
- Three chronograph subdials
- Hardlex crystal
- Numberless dial with applied indices
First Touch: The bracelet feels solid—no rattling or flimsiness. The case has weight to it, though experienced watch enthusiasts will immediately recognize it's not stainless steel. The pushers operate with satisfying clicks. The crown feels adequate but not premium.
Reality Check: This watch tries to do everything. The question isn't whether it looks impressive (it does), but whether all these complications actually work reliably.
Design & Build Quality: Ambition vs. Execution
Case Construction
Specifications:
- Material: Alloy (not stainless steel)
- Shape: Round
- Diameter: 40-44mm (measures approximately 43mm)
- Thickness: 11mm
- Weight: Approximately 100-110g
- Crown: Push-pull (non-screw down)
- Pushers: Two chronograph pushers
- Water Resistance: 3 Bar
The Alloy Trade-Off: The BY-5198 uses an alloy case to hit the $75 price point while adding the stainless steel bracelet. This is a strategic choice:
Why Alloy for the Case:
- Keeps weight manageable
- Allows budget for stainless bracelet
- Reduces overall cost
- Makes adding complications financially viable
The Compromise:
- Scratches more easily than stainless steel
- Less premium feel than full stainless construction
- Lower long-term durability
- Shows wear faster
Real-World Durability (After 2 Weeks):
- Minor surface scratches visible on case
- Some scuffing on polished bezel edges
- No structural issues
- Complications all functioning
Honest Assessment: At $75 with this many features, something had to give. The alloy case is the sacrifice that makes everything else possible.
Dial Layout: Organized Chaos
The dial is the star—and the challenge—of the BY-5198:
Dial Features:
- Blue sunburst dial (other colors available)
- Numberless design with applied hour indices
- Moonphase display at 6 o'clock
- Day window at 10 o'clock
- Date window at 3 o'clock
- Three chronograph subdials
- Multiple hands (hour, minute, second, chronograph)
- Luminous hands
Legibility: 7/10
There's a lot happening on this dial. BENYAR did a reasonable job organizing it, but reading time requires a moment of focus—this isn't a glance-and-go watch. The subdials are clearly defined, but distinguishing between the various hands and complications takes practice.
Color Impact: The blue sunburst dial is gorgeous in proper lighting. It shifts from deep navy to bright blue depending on angle and light. This is a premium-looking finish that significantly elevates the watch's perceived value.
Complexity Assessment: If you appreciate intricate dials and enjoy complications, this delivers. If you prefer minimalist clarity, this will feel cluttered.
The Complications: Do They Work?
Let's examine each complication individually:
Moonphase Display
Location: 6 o'clock position
Function: Displays current lunar phase
Performance: Actually works (rotates through lunar cycle)
How Accurate? The moonphase advances correctly with the date. It will drift approximately one day every 2-3 years—standard for this type of mechanism.
Practical Value: Limited for most users. It's primarily aesthetic and conversational. Unless you're tracking tides, fishing, or just love astronomy, it's more "cool feature" than "essential function."
Complete Calendar
Windows:
- Day of week (at 10 o'clock)
- Date (at 3 o'clock)
Performance: Both advance correctly at midnight (tested multiple nights). Quick-set function works via crown positions.
Monthly Adjustment: Requires manual adjustment for months with fewer than 31 days (like February, April, etc.).
"Perpetual Calendar" Claim
Marketing vs. Reality: The listing claims "perpetual calendar," but this is a misnomer. A true perpetual calendar automatically adjusts for varying month lengths and leap years—mechanisms that cost thousands of dollars.
What This Actually Has: A complete calendar (day + date) that requires manual adjustment for short months. It's an annual calendar at best, not perpetual.
Honest Assessment: This is marketing language inflating what the watch actually offers. It's still a useful calendar, but not perpetual in the horological sense.
Chronograph Function
Controls:
- Top pusher: Start/stop
- Bottom pusher: Reset
- Crown positions: Time, date, day setting
Subdials:
- Left: 24-hour indicator
- Top: 30-minute chronograph counter
- Right: Chronograph seconds
Performance: The chronograph operates smoothly. Pushers have good tactile feedback. Hands reset to zero accurately. For casual timing needs, it works perfectly.
Rattrapante Claim: The listing mentions "rattrapante" (split-seconds chronograph), but testing reveals this is standard chronograph functionality, not true rattrapante. Another case of marketing overreach.
Hardlex Crystal: Solid Protection
Performance After 2 Weeks:
- Zero visible scratches
- Good clarity
- Adequate scratch resistance
- No anti-reflective coating
The Hardlex crystal is a genuine positive. It's held up well through daily wear and provides better protection than basic mineral glass.
Stainless Steel Bracelet: The Quality Highlight
Specifications:
- Material: Stainless steel
- Width: 15-19mm (tapers)
- Length: 22cm
- Links: Solid construction
- Clasp: Push-button hidden clasp
Quality Rating: 8/10
The bracelet is where BENYAR invested the build quality:
What Works:
- Genuine stainless steel
- Solid links (no rattling)
- Comfortable taper from lugs to clasp
- Push-button clasp feels secure
- Good weight distribution
- No sharp edges
Minor Issues:
- Sizing requires tools (screwed pins)
- No micro-adjustments
- Clasp could be slightly more robust
Comfort: After proper sizing (I removed two links), the bracelet is comfortable for all-day wear. The push-button clasp is convenient and secure.
Movement & Functionality: Quartz Reliability
The BY-5198 uses a Japanese quartz movement with complications module.
Timekeeping Accuracy
Testing Period: 14 days
Result: +4 seconds total drift
Projected Accuracy: ±10-15 seconds per month
Excellent accuracy. The complications don't affect timekeeping precision.
Complications Reliability
What Works:
- Moonphase rotates correctly
- Calendar advances at midnight precisely
- Chronograph operates smoothly
- All hands reset properly
What Requires Attention:
- Manual calendar adjustment needed monthly
- Moonphase needs adjustment every ~2.5 years
- Quick-set positions require gentle operation
Battery Life Expectation
With this many complications, battery life may be shorter than simple quartz:
- Expected: 18-24 months
- Standard quartz: 24-36 months
The additional complications draw more power. Plan for more frequent battery changes.
Water Resistance: Basic Protection Only
Rated: 3 Bar (30 meters)
Reality: Splash-resistant, nothing more
✅ Safe For:
- Handwashing
- Light rain
- Brief splashes
- Normal humidity
❌ NOT Safe For:
- Swimming
- Showering
- Water sports
- Operating pushers when wet
CRITICAL: Never operate chronograph pushers when the watch is wet. Water can enter through unsealed pushers.
Assessment: For a watch branded "sports chronograph," 3 Bar is disappointing. This is a dress chronograph, not a sports tool.
Wearing Experience: Wrist Presence
Fit & Comfort
Wrist Size Recommendations:
- Minimum: 6.5"
- Ideal: 7" - 7.5"
- Maximum: 8"+ (22cm bracelet accommodates)
I tested on a 7.25" wrist and found the fit excellent. The 43mm case is well-proportioned without overwhelming.
All-Day Comfort: The 100-110g weight is noticeable but not fatiguing. The 11mm thickness allows it to slip under most shirt cuffs. The bracelet distributes weight well.
Activity Performance:
Office Work (daily):
- Professional appearance
- Comfortable typing
- Complications occasionally distract (in a good way)
- Blue dial catches compliments
Casual Wear (weekends):
- Works with smart casual
- Too dressy for athletic wear
- Good conversation starter
- Moonphase always draws attention
Not Tested For: Genuine sports activities (water resistance too limited)
Styling Versatility
Works Great With:
- Business casual (chinos and button-down)
- Smart casual (blazer and dark jeans)
- Date nights
- Semi-formal occasions
- Weekend brunches
Marginally Works With:
- Business formal (complications may be too busy)
- Suits (depends on industry culture)
Doesn't Work With:
- Athletic/sportswear (too dressy)
- Black tie formal (too complicated)
- Outdoor/rugged activities (water resistance inadequate)
- Beach/pool (not water-safe)
Style Assessment: Despite "sports chronograph" branding, this is a dressy complication watch for casual to business-casual wear.
