Why Upgrade from the A6 Compressor?
The original A6 piston compressor is heavy, inefficient, and increasingly difficult to find parts for. The Sanden rotary compressor offers:
- Less engine load — lighter weight means less parasitic drag
- Better cooling efficiency — especially at low RPMs during field work
- R134a compatibility — works with the modern, readily available refrigerant standard
- Widely serviceable — any shop with modern A/C equipment can service a Sanden system
Installation Notes
- Flush the system before installing to remove residual mineral oil from the old A6 system
- Use PAG oil specified for the Sanden compressor — do not mix with old mineral oil
- Replace all O-rings with HNBR (green) O-rings rated for R134a (included in kit)
- Have the system professionally evacuated and recharged with R134a refrigerant

Nice quality with great pockets
My husband loves these shorts. Particularly the pockets with button closure. You can easily fit a cell phone, money clip, or loose change. The material is soft and comfortable. I ordered them in this color and white.

Shorts
Color: Sky Blue, Size: 36
Love these shorts, I was very happy with the look, color, weight, and fabric quality. Great value. I wish they had a light pink color in the same style and fabric.

Practicality First
Color: Brown/Black, Color: Brown/Black
This is a simple, no frills watch from a well regarded brand.
It has good water resistance, good durability, and high accuracy.
If all you need is a way to tell the time that won’t fail you, buy this watch.
As it’s solar powered, it doesn’t need to be wound or have a battery replaced or charged in the foreseeable future. This longevity and low effort maintenance was the most important feature for me, and part of why I chose this over a digital watch (along with digital watches potentially being bricked from firmware).
I shouldn’t have to say this but obviously it doesn’t come out of the box charged and working - you need to leave it by a window or something for a day. After that, it will always work so long as you wear it outside every so often. The battery life is claimed to be 2 months but I’m not about to leave it in a closet for 2 months to test this. This is a newer model than the version I’d been trying to buy and it appears to have a more readable face as well as luminescent watch hands which are helpful for telling the time in the dark. It’s also nearly silent so ticking won’t be an issue.
My only complaint is the watchband. It’s a serviceable quick release band, but it’s a bit on the short side and I wanted something of higher quality so I replaced it with a Hirsch 120mm/100mm watchband that actually fits and is altogether nicer than the out of the box band.

The simplest watch there is
Color: Khaki/Black, Color: Khaki/Black
I have a 7-inch wrist and I would like to think that it's the average size (judging from the pictures I have seen from other reviews.) The watch came in from Amazon with zero charge so I charged it for about an hour using a solar watch charger and that brought it back to life. I found that you could charge a solar watch from empty to full in about 5 hours. What I like about this watch is that it fits and feels right on my wrist, is not ostentatious, not flashy, and doesn't crave for attention. You could read the time very well outdoors and even indoors. Even in the dark, the lume is laid-back, but you could still tell the time from the triangular hour markers and the hour and minute hands of the watch. I also like that it has a screw-down case back. I like to tinker with my gadgets and a screw-down case back allows me easy access to the battery when it's time to be replaced. It's also solar-powered, has a 4-month power reserve, an easy-to-operate crown, and has sapphire crystal to boot!
Fun fact: I found out recently that they made these watches in Timex's watch factory in Cebu, Philippines. By purchasing it from Amazon, it actually did a return trip back here in the Philippines!
Update after a month's use: I changed the strap with a black NATO one and it looks even better with the matte finish of the case. The charge appears to remain strong. I'll probably notice the weird erratic second hand movement (the watch does this when the charge is about to drain) after 4 months. Until then, it's not time for a recharge.
