Tiangong Kaiwu: Chiyou Butterfly Double Snap Button Leather Strap Unpacking & Retrofitting Quick Release Ear

Read the catalog

Last year bought a Withings Activité with a third-party iStrap strap. There have been nearly nine months of service, and there are not many articles on value-for-money original purchases on leather straps. This time, the rebranding has re-elected a brand: “Excellent Productivity”.


Out of the box


Two free upgrades to SF, arrived the next day across the province.

Two straps (second half price), plus a product description, a service card.

Brand new packaging, each package comes with a raw batch, comes with a raw ear and a leather apron.


Manufacturer information, uniform retail price: ¥ 200.

Redesigned hole spacing does not require a complimentary hole puncher for a variety of wrist sizes.

Four-legged buckle + double spring, this is my main reason to lock this strap, high-end brand butterfly double snaps are almost all four-foot buckle.

This strap is thin and it will quickly adapt to the shape of the wrist. It will not feel hard to wear.

Rebuild quick release ear

Raw ear, is the word of watch profession circle. Refers to the link bar between the fixed strap and the watch dial. Ninety percent of watches are fixed by raw ear. The work of dismantling raw ears is called raw ear batch.

Quick-release ear, you can not need to ear batch work, use your fingers to install or replace the strap. If a watch usually replaces the watchband more frequently, using the quick-release ear can be a lot easier.

The following figures are raw ear, ear batch, quick release ear.

Quick release ear comes from the Withings Activité strap, Taobao also sells.

The use of tools is a sculpting knife, and ordinary utility knives are also available.

After the quick-release ear is installed, there is a small pin that can be toggled on the strap, which has no effect on the durability and service life of the strap.

With reference to the Withings Activité strap, a slot of the same size is engraved on the accumulating strap and the quick-released raw ear is inserted and the operation is completed.

Accumulation VS iStrap

Both have obvious differences between the butterfly double snap and the leather strap itself.

Excellent product: four-foot buckle buckle strap light without Logo

iStrap: Grip with two straps Logo with Logo


Purchase suggestion

The quality of the carton pack is general, and the inner box is flocked and napped. Buy two tables but send a set of product descriptions.

The advantage of this strap is that the double button design of the butterfly is higher than that of other grades, and the actual use is also more solid.

The strap is a very thin style, use soft. However, the brand's logo was not printed on the back of the strap, which lowered the value of the brand and was suspected of OEM OEM products.

The original price of ¥88, the second half price, the actual price of each ¥66, high cost performance. Refund method is to confirm receipt, contact customer service cash back. The explanation of the business is that other than freight, other prices cannot be changed.

Tucao: In the process of my cashback, I encountered the customer's promise to return the money within 48 hours. If I did not write this original, I forgot to check the refund. There are certainly many consumers who even forget to contact customer service. The merchant’s sales return method is poor.
