Who should buy which.
The Urban Date Aurora Green: A first-time automatic buyer who wants a green date dial, sapphire and a manufacturer-listed 72-hour reserve at an accessible tested price. Choose a smaller case if 41.5 mm feels broad, a bracelet if you do not want leather, or a higher water-rated model for regular swimming or water sports.
The SHY042 40mm NH35A Diver (Black): A buyer who wants a first mechanical diver in a classic 40 mm size at a low price. Choose a thinner watch if you wear slim cuffs, or a titanium diver if weight matters.
Before you order.
The 41.5 mm case is not small, and BODERRY does not publish a lug-to-lug measurement for this reference. The supplied strap is leather and the water rating is 5 ATM / 50 m; the product page does not set out a specific swimming-use promise. Choose it for everyday wear and ask the brand about your intended water exposure.
At 13.6 mm thick it wears chunkier than its 40 mm diameter suggests. THORN gives no rated power reserve and no ISO dive certification, and lists the water rating as its own specification.
