Proper installation guarantees better performance, follow these suggestions for installation.
- For power connections use only good cables, of suitable sections and protected in the engine compartment. The cables for car-audio applications are very flexible and therefore easy to install.
- Carefully take care of the laying of the cables and operate in order to follow different routes to signal cables from power cables.
- It is a good idea that the mass of the amplifiers is connected to the same point, together with the car radio's one.
Example: if there are two amplifiers in the trunk, find a good grounding point for the amplifiers themselves and bring the mass of the car radio to the same point using a cable (3-5mm).
- Fix the voltage stabilizer securely, to avoid its movement and then the cables jostling.
- A well-designed and equipped system may involve the collection of various devices, if this happens, ensure adequate ventilation of the place where the amplifiers are installed, perhaps with the aid of an additional forced air flow by a fan inside the various compartments if is need.

Keeps lousy time
Color: Silver-Tone/Black
I purchased this watch off Amazon Warehouse well below MSRP out of curiosity to see what Timex is doing in 2024. The specs are good - bead blasted stainless case, solar movement with quick set date and hacking, sapphire crystal, screwdown crown and 100m water resistance. The movement is Japanese, case and bracelet are made in China, and the watch is assembled somewhere overseas.
The good - the watch is lightweight and comfortable on the wrist. Price, even at full MSRP makes this an extremely good value for what you get. It is a good looking Flieger style watch. Once fully charged it is keeping good time. Case finish is well executed and without rough or sharp edges.
The bad - the lume is weak. When blasted with UV, it fades quickly and within 5 minutes it’s gone. The bracelet is low end, but expected at this price point. I swapped it out with a nice leather strap from my collection with better quality spring bars and it makes the watch look and feel higher end.
The Ugly - the second hand misses nearly all the chapter ring marks. The minute and hour hands are aligned, but that second hand seems to have a mind of its own. On my watch it lines up with chapter ring marks maybe 10% of the time, but it’s not consistent.
Sum up, for a sub $200 watch the specs are great and it’s a good looking comfortable watch. Just keep your expectations aligned with what you are paying for. It compares favorably to Orients & Citizens at this price, and offers better value than comparable competitors now that Seiko has gone upmarket. I like this watch. Just don’t compare it to a Swiss watch costing several times its price.
Update after a few months: I’m changing my rating to 3 stars. This watch keeps lousy time! It is loosing around 5 minutes per month. And it is fully charged. I have other Solar quartz watches from Citizen, Seiko and Vaer which maintain very good accuracy. But this Timex … defeats the purpose of a solar powered “grab and go” watch when you have to correct the time each occurrence you want to wear it.

Great Watch with Great Sapphire Crystal
Color: Olive/Gunmetal
Waited 2.5 years before reviewing. I love the gunmetal grey case, olive dial, and the exceptional sapphire crystal. The watch is still running great. During cold weather when wearing long sleeves, I make sure I charge the watch monthly by placing it under a table lamp for many hours because it died once due to no daylight charging. One problem is being able to see the minute markings. (The same watch with blue dial is much easier to read.) I also replaced the military-style band immediately with the excellent Archer 20mm Olive band (ARC-QRN-OLV20) and Archer 20mm Matte Gunmetal buckle ( ARC-BKL-GRYM20). I am only allowed to review once for this Timex model, so adding comments about the "Blue" version (TW2V03600JR). The blue version is the same watch but easier to view. It looks GREAT with the Archer 20mm Navy Blue band (ARC-QRN-NVY20).

I design flaw caused me to return it.
Color: Brown/Blue
Pros:
- Perfect case size.
- Sapphire crystal.
- Solar powered quartz.
- Large dial face
- Minute and second hands reach to minute track for precise reading.
- Great field watch design and proportions.
- Effective lume on hands.
Cons:
- Lume on small triangular hour markers is useless, and fades quickly.
- The hour numbers are not luminous.
- The dull peach color chosen for the hour markers, numbers and hands in dim lighting is very dull and thus hard to read.
- The dark blue color chosen for the dial is a dull hue that doesn’t really look blue, but just reduces the contrast between text and markers.
- A black dial and bright white markers and numbers would make the watch much more legible/ readable, and would look much better aesthetically. It is a shame that these choices were made on an otherwise perfect design.
- I was really excited that Timex finally seemed to get it when they came out with this series of models, but then they handicapped it with a dial that is only useable in bright light. What a shame.
I am returning the watch.

Look and feel awesome!
Size: 11.5, Color: Optic White/Opti
These are awesome shoes - look great really, really white and clean! Love how comfortable they are - and soooo light. I was a little worried they'd get dirty easily, but I've been able to keep them clean. Fit as expected. If you're looking for a great, comfortable, and affordable shoe, check these out!

Great shoe, comfort
Size: 11.5, Color: British Tan/Ivry
Love these shoes, they're super comfy. Laces stayed tied all day. I wear them in a business casual environment, or if I'm going out for a nice meal with my wife. They look good, the color is unassuming and neutral. they also elevate my height, I feel like it gives me an inch or so more versus regular shoes. This is my second pair!
