Audemars Piguet Royal Oak Lady Automatic – Stainless Steel | Reference 8638ST

A Rare and Historic Lady Royal Oak from the 1970s

This vintage Audemars Piguet Royal Oak Lady Automatic, Reference 8638ST, represents the very first Royal Oak designed specifically for women. Introduced in 1976, the 8638 carried forward the revolutionary design language of the 5402 “Jumbo” of 1972, reinterpreted in a refined 29 mm case suited for a female clientele.

Crafted entirely in stainless steel, the case remains exceptionally sharp, with crisp bevels and the iconic octagonal bezel featuring exposed screws. The integrated bracelet, also in steel, is long and accommodates a wrist size of approximately 17–17.5 cm—rare for this reference and highly desirable for collectors.

Powered by the Self-Winding Calibre 2062

At its heart is the Audemars Piguet Calibre 2062, a compact yet robust self-winding movement based on a LeCoultre ébauche, celebrated for its slim architecture and reliability. This movement has benefited from multiple services over the years, supported by a wealth of accompanying documentation.

Brown Tropical Dial – Even and Beautifully Aged

The original dial has aged into a completely even tropical brown tone, lending the watch a warmth and individuality that can only develop over decades. Applied tritium hour markers and hands remain intact, adding depth and vintage character.

It definitely is fiber
Flavor Name: Original Coarse Sugar, Size: 1.86 Pound (Pack of 1)
It is nice to take a break from the orange flavoring they have with the original one, and the sugar does help it go down easier, but please for your sanity DO NOT DRINK THIS WITH JUST PLAIN WATER. I like to mix it up in flavored water with those sugar free drops that let me control what flavor the water is without suffering from raw dogging the unflavored powder because that will taste like drinking a glass of sand. Next time I'll try out the clear blend without any sugar to see if there's a difference, but this bottle will last a while. Also be gradual with introducing it into your diet and work up to a few teaspoons throughout your day to not overload your body. All that aside, it works well and my body feels more comfortable with the extra fiber in my life. I highly recommend some form of this because it's really tough to get enough fiber in many diets.

Unflavored but sweetened Metamucil
Flavor Name: Original Coarse Sugar, Size: 1.86 Pound (Pack of 1)
If the orange flavored Metamucil is too acidic for you but you want a sweetened unflavored variation, this is just right. It is sometimes hard to find and is often sold out at the drug store or grocery store. I was glad to find it on Amazon.

Unflavored original texture with sugar is the best!
Flavor Name: Original Coarse Sugar, Size: 1.86 Pound (Pack of 1)
I don't why the fake orange flavor is so popular. Unflavored is neutral and agreeable. Even with the sugar this product is very low glycemic index because the tiny amount of sugar is offset by the fiber.

Works but VERY thick
Flavor Name: Original Coarse Sugar, Size: 1.86 Pound (Pack of 1)
Thought I was ordering the orange flavor, which I can drink, successfully. The unflavored, sugar free is what I actually ordered. My fault, not the seller, but the difference, for me is huge! I can't choke it down. Flavor is completely neutral, it isn't that. But, seems so much thicker than the orange. ? Maybe it isn't, could be that the thickness of the orange is same but I can trick myself into thinking its orange pulp. Who knows. But, in any event, the unflavored definitely seems like I'm drinking mud. I can't do it. Too bad, too, because the product is VERY effective. I have colitis/IBS and the Metamucil brand works so much better than anything I've tried, in helping with GI issues, in general. Increased regularity, more comfortable passing, and over time, a GI cleansing that you can actually feel. I highly recommend the product, but you might want to pay extra for the orange flavor. Might make the difference in you being able to drink it with the consistency required for best results.
